Summary: When using a medium (500) font weight on Android the wrong weight is used for the placeholder and for the first few seconds of input (before it gets text back from JS). To fix it I refactored the way we handle text styles (family, weight, style) to create a typeface to be more like the `Text` component. Since all these 3 props are linked and used to create the typeface object it makes more sense to do it at the end of setting props instead of in each prop handler and trying to recreate the object without losing styles set by other prop handlers. Do do that we now store fontFamily, fontStyle and fontWeight as ivar of the ReactEditText class. At the end of updating prop if any of those changed we recreate the typeface object. This doesn't actually fix the bug but was a first step towards it. There were a bunch of TODOs in the code to remove duplication between `Text` and `TextInput` for parsing and creating the typeface object. To do that I simply moved the code to util functions in a static class. Once the duplication was removed the bug was fixed! I assume proper support for medium font weights was added for `Text` but not in the duplicated code for `TextInput`. ## Changelog [Android] [Fixed] - Fix medium font weights for TextInput on Android Pull Request resolved: https://github.com/facebook/react-native/pull/26434 Test Plan: Tested in my app and in RNTester that custom styles for both text and textinput all seem to work. Repro in RNTester: ```js function Bug() { const [value, setValue] = React.useState(''); return ( <TextInput style={[ styles.singleLine, {fontFamily: 'sans-serif', fontWeight: '500', fontSize: 32}, ]} placeholder="Sans-Serif 500" value={value} onChangeText={setValue} /> ); } ``` Before:  After:  Reviewed By: mmmulani Differential Revision: D17468825 Pulled By: JoshuaGross fbshipit-source-id: bc2219facb94668551a06a68b0ee4690e5474d40
