e38801b1 - Reapply "[clang][ModulesDriver] Add support for Clang modules to -fmodules-driver" (#191258)

Reapply "[clang][ModulesDriver] Add support for Clang modules to -fmodules-driver" (#191258) This relands #187606 (reverted with #191122). In the initial PR, the Clang module precompile jobs were created as `CC1Command` objects instead of regular `Command` objects, which introduced a memory leak. (See discussion in https://reviews.llvm.org/D74447) This has been fixed in this reland.
