With this, we send the correct x position when using center or right aligned text. In order to accomplish this though, we have to pass the text alignment into the Layout object that we create.
Also update RNTester to allow us to try different alignments.

I tested the following on my physical device (Sony Z5C) and on Android emulator on Mac.
The test app contains various fonts in the AvenirNext family, which are added to the app as `.ttf` format.
Note that the character "thickness" is inconsistent. Some characters looks thicker than other. See the screenshots below as an example:
- Looks thicker: right half of the `g` and `&` as in "Region & Language" (list-view screen)
- Looks thicker: `w` as in `Change Password` (list-view screen)
- Looks vertically compressed: `a` and `e` as in "Message" in the bottom bar (list-view screen)
- Looks thicker: `A`, `N`, `V`, `v` (paragraph screen)
- Looks thinner: `i` (paragraph screen), it leaves extra space on its right hand side
Every characters has consistent "weight" and looks nice:

Summary:
@public
As we're doing in D9440914 (OSS 64a52532fe), send text metrics in an onTextLayout callback. These can be used by surrounding views for doing complicated layout like:
- displaying a cursor at the end of text
- vertical centering using capheight-baseline
This right now isn't very performant but is only done when `onTextLayout` is set. I plan to optimize it with a capheight and xheight cache in a follow up diff.

Summary:
There seems to be a rounding error in the android code for line height, so that for some fonts and at some combinations of line height and font size the actual height of the elements seems to be slightly too short.
I've identified one issue that I mentioned here https://github.com/facebook/react-native/issues/10712#issuecomment-359382137 that could at least explain some of the problem. That when the line-height minus the original sum of the absolute value of top and bottom from the metrics, happens to be an odd number, the division by two causes a rounding error of 1, so that the actual line height is 1pt less than it should.
The fix uses floating point division instead of integer division, and rounds (arbitrarily) the negative values up and the positive values down so that the total is still the correct for odd numbers.
It turns out that only ascent and descent is used to give the actual line-height between lines in the same text-element. The top and bottom values are only used for padding the top and bottom of the text. So when the line-height is greater than the font size and the extra padding this PR sets the ascent and descent to the same value as the top and bottom respectively.
I've renamed the shouldIncreaseAllMetricsProportionally test to evenLineHeightShouldIncreaseAllMetricsProportionally and added an extra assertion to check that bottom-top still equals the line height.
Added another test oddLineHeightShouldAlsoWork that is similar but uses an odd number for the line height to test that it still works with odd numbers. This test only uses the sum of the values so that it's indifferent to what value the implementation chooses to round up or down.

Summary:
We noticed that on Android the lineHeight behaviour is different from iOS for built in fonts and custom fonts. The problem becomes visible when the lineHeight approaches the fontSize, showing a cut-off on the bottom of the TextView. This issue has been raised before in #10712. There is a mention of a PR with a fix in that issue, which has not been merged yet. This implementation is a less intrusive fix leaving the current lineHeight approach in place and fixing the discrepancy only.
This proposed change prioritises ascent over descent for reduction, making the lineHeight functionality behave identical to iOS.
There is no existing test covering the lineHeight property and its behaviour in the CustomLineHeightSpan. This PR contains new unit tests that covers the various scenario's for the lineHeight calculations.
The original behaviour, before the change can against these unit tests. The case that fails is `shouldReduceAscentThird`, which can be made to succeed on the old code by changing the asserts to:
```
assertThat(fm.top).isEqualTo(-5);
assertThat(fm.ascent).isEqualTo(-5);
assertThat(fm.descent).isEqualTo(-4);
assertThat(fm.bottom).isEqualTo(-4);
```
The unit test succeeds for the current implementation, which has the values for ascent and descent inverted.

Summary:
When we convert nested <Text> components to Spannable object we must enforce the order of spans somehow,
otherwise we will have Spannable object with unpredictable order of spans, which will produce unpredictalbe text layout.
We can do it only using `Spannable.SPAN_PRIORITY` feature because Spannable objects do not maintain the order of spans internally.
We also have to fix this to implement autoexpandable <TextInput>.

Summary:
Abstract class `ReactBaseTextShadowNode` was decoupled from `ReactTextShadowNode` to separate two goals/roles:
* `ReactBaseTextShadowNode` represents spanned `<Text>` nodes, which can bear text attributes (both `RCTText` and `RCTVirtualText`);
* `ReactTextShadowNode` represents anchor `<Text>` view in Yoga terms, which can bear layout attributes (`RCTText` and `RCTTextInput`).
`ReactVirtualTextShadowNode` now inherits `ReactBaseTextShadowNode`.
The same architectural changes was applited to view managers.
Why?
* This is just a better architecture which represents the nature of this objects.
* Bunch of "negative" logic which turn off excessive features for some suclasses was removed.
* Memory efficiency.
* Now we can improve `<TextInput>` component using right inheritance. Yay!

Summary:

So, we must not interit it from HUGE ReactTextShadowNode (which represents <Text> node with ReactRawTextShadowNode instance inside).
We need this change to make future fancy (and valuable from product perspective) refactoring possible. Stay tuned!

Summary:
Overview -
This PR resolves the issue described in #14606. This PR makes Text components take into account the includeFontPadding property when calculating their size.
Background -
Currently, on Android, when includeFontPadding is set to false, the React Text component does not adjust its height. This makes it difficult to lay out other components at a precise spacing relative to a Text component.
iOS calculates the height of a UILabel based on the font's descent + ascent.
Android lets you choose whether to calculate the height of a TextView based on the font's top + bottom (includeFontPadding=true) or ascent + descent (includeFontPadding=false).
In order for a text component to be the same size on iOS and Android (relative to the rest of the layout in points and dips), one should set includeFontPadding=false on Android - but the React Text component needs to take this property into account when sizing itself for this to work.
Please see this stack overflow post for a visual explanation of the difference between a font's ascent/descent and top/bottom - https://stackoverflow.com/questions/27631736/meaning-of-top-ascent-baseline-descent-bottom-and-leading-in-androids-font
Testing -
Please see the attached screenshots to see the height difference of a Text component with this PR when includeFontPadding is true vs false.
The font I am using has an ascent + descent = em-size so that the height of the Text component will be equal to the font-size for a single line of text. This is to clearly show the additional height that includeFontPadding=true adds to the Text component.
For Text components that are styled in the same way,
When includeFontPadding=true, height = ~29.714 dips
When includeFontPadding=false, height= 24 dips

Summary:
Make android-version accept a decimal
number as lineHeight.
Credits where due, solution was given in this
issue: facebook/react-native#10607
According to the w3 spec the property
line-height should accept decimal values
(and it does on iOS) but the android
version has the wrong data-type for the
shadowed method, resulting in a stacktrace
saying:
com.facebook.react.bridge.UnexpectedNativeTypeException: TypeError:
expected dynamic type `int64', but had type `double'
Setting it to a float makes it accept
decmial values as it should.
* Create an app without this commit and create the same app with this commit:
In both apps:
- Leave line-height undefined. Behavior is unaffected by this commit.
- Set lineHeight to a integer number. Behavior is unaffected by this commit.
- Set lineHeight to a decimal number. Line height is now rendered with decimals in the app with this fix.
* Run android integration tests to see nothing
else broke.

Fixes#11592
This bug was seen on a Galaxy S4 running Android 4.4.2. On this device, Android's `Layout.getDesiredWidth` method doesn't correctly measure text that contains unicode emoticons. It appears to think the emoticons take up 0 space.
Setting ANTI_ALIAS_FLAG in the TextPaint's constructor instead of setting it later with setFlags works around the Android bug.
