fix oss build

Summary:
Fix the OSS. Mostly adding files related to components and fixed size index in cmake files. Also upgraded gcc to 14 for best coroutine support.

C++20 coroutines were a major new feature. The compiler has to do complex transformations to turn coroutine code into a state machine (the "coroutine frame lowering" pass). In GCC 11, this transformation has bugs.
