[LOCAL] Make rrc_textinput on Android a shared library

[j-piasecki]

Summary:

Making rrc_textinput allows other libraries (namely react-native-live-markdown) to rely on types related to text inputs on Android. Currently, with static linking, type information is duplicated causing dynamic_casts to fail.

Changelog:

[ANDROID] [CHANGED] - Change rrc_textinput to be a dynamic library

Test Plan:

Run RNTester and see that everything works as before

@j-piasecki I think we won't be merging this as we're going in the opposite direction of having a single libreactnative.so library.
