[CMake] Give a dedicated component to compiler swift-syntax libraries (#76497)

* [CMake] Give a dedicated component to compiler swift-syntax libraries

'compiler-swift-syntax-lib' so projects statically link to compiler
libraries (libAST etc) can use the required shared libraries.

rdar://135923606

* Update cmake caches

* Add back implicit `swift-syntax-lib` to `compiler` component for now

Some clients doesn't specify `swift-syntax-lib`.
