Summary:
These assertions will already run by default on iOS, macOS, Windows, etc, all OSes except Android because of a longstanding Buck+Android NDEBUG issue.
Align platforms by using REACT_NATIVE_DEBUG flag.
Only impacts debug/dev builds.

Summary:
BUCK always defines NDEBUG on Android builds. This is a longstanding issue and it's tricky to work around.
Previous attempts to fix this within React Native were difficult because disabling NDEBUG caused lots of issues that were difficult to track down.
Instead, I am (1) introducing a new RN_DEBUG flag that can be used cross-platform, (2) whenever NDEBUG is *not* enabled, RN_DEBUG will automatically be defined, (3) enables debug-only code to be compiled on Android, (4) enables us to selectively, slowly migrate `assert` to `rn_assert` in a way that doesn't impact non-Android platforms, but allows us to maintain stability of Android debug builds.
Actually enabling the RN_DEBUG flag in debug builds is done in FB-internal code. I assume the NDEBUG issue is not a problem when compiling in open-source without BUCK.
