Address New Architecture performance regressions by properly setting NDEBUG ( #36172 )
...
Summary:
It looks like we're not properly setting `NDEBUG` for "non debug" builds with CMake (the name is terrible but that's what Buck uses originally).
This configures `NDEBUG` correctly so that is set only for release variants, so that also `REACT_NATIVE_DEBUG` is set correctly (and we don't fire asserts on release builds).
This should address several performance regression we saw for New Architecture on some release scenarios (credits to sammy-SC for spotting it).
## Changelog
[ANDROID] [FIXED] - Address New Architecture performance regressions by properly setting NDEBUG
Pull Request resolved: https://github.com/facebook/react-native/pull/36172
Test Plan:
I've tested this by checking the ninja output for the debug/release builds for the `YogaLayoutableShadowNode.cpp` file

Introduce RN_DEBUG flag and rn_assert for Cxx
...
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.
