[clang] [clang] Rename ReadPCHAndPreprocessAction (NFC) (PR #122390)

[Steven Wu via cfe-commits]

https://github.com/cachemeifyoucan created https://github.com/llvm/llvm-project/pull/122390

Rename `ReadPCHAndPreprocessAction` class. This frontend action is used
for dependency scanning only and the current name is confusing for what
it actually does. Rename the class to `DependencyScanningFrontendAction`
to be clear for its usage.
