[llvm] [flang][docs] Add flang to full list of projects in top-level LLVM CMake docs (PR #221962)

[Matt Bolitho via llvm-commits]

https://github.com/MattBolitho created https://github.com/llvm/llvm-project/pull/221962

The top-level LLVM CMake docs do not include `flang` as a valid value for the *full* list of projects valid for `LLVM_ENABLE_PROJECTS`, even though it is per the `flang` project documentation.

     Some projects listed here can also go in `LLVM_ENABLE_RUNTIMES`. They should only appear in one of the two lists. If a project is a valid possibility for both, prefer putting it in `LLVM_ENABLE_RUNTIMES`.
