[clang][deps] Use MemoryBuffer in minimizing FS
This patch avoids unnecessarily copying contents of `mmap`-ed files into `CachedFileSystemEntry` by storing `MemoryBuffer` instead. The change leads to ~50% reduction of peak memory footprint when scanning LLVM+Clang via `clang-scan-deps`.
Depends on D115331.
