5c928535 - [clang] Store size & mtime in in-memory module cache (#190207)

[clang] Store size & mtime in in-memory module cache (#190207) In this PR, the in-memory module cache now stores the size and modification time of PCM files. This is needed so that the `ModuleManager` doesn't need to consult the file system to obtain this information, which _might_ be in a different state than when we stored the PCM file buffer into the in-memory cache.
