Summary:
This adds support for `<Picker style={}/>` prop for text styling. It reuses most of conversion logic from BaseText. This means that it actually supports more styles than Paper Picker supported. (Paper picker only supported ~4 styles, this supports everything that Text supports, so 10+ styles).
The only tricky thing is that Picker supports multiple ways of setting text color. Both
<Picker
itemStyle={{color: '#008BD0'}} >
<Picker.Item label="Java" value="java" />
<Picker.Item label="JavaScript" value="js" />
</Picker>
and
<Picker>
<Picker.Item label="Java" value="java" color={'#008BD0'} />
<Picker.Item label="JavaScript" value="js" />
</Picker>
technically work in Paper. I've decided to maintain this behaviour (since there's lots of product code callsites to both options).

Summary:
This is a starting point for the handwritten Fabric Picker component. It is incomplete, and needs to be landed with the rest of the stack above it.
In general, this creates a new `ComponentView`, `ComponentDescriptor`, `ShadowNode`, `Props` and a few other boilerplate classes for Picker. A bunch of the logic in `ComponentView` was copied over from the Paper `RCTPicker` and `RCTPickerManager`.
What works in this diff:
- A `<Picker>` with items can be created in JS, and a corresponding `UIPicker` is created in native with placeholder text, default styling and the correct amount of items
What doesn't work yet (implemented in later diffs):
- Parsing items to use correct text and styling in native
- Events/commands
