0e35f56d - [clang][Dependency Scanning][NFC] Move `DependencyScanningAction` to its own header and source files (#160795)

[clang][Dependency Scanning][NFC] Move `DependencyScanningAction` to its own header and source files (#160795) This is the first of three PRs to land https://github.com/llvm/llvm-project/pull/160207 in smaller pieces. This PR is an NFC. It moves `DependencyScanningAction` to its own source file, so we can later implement a `CompilerInstanceWithContext` in the new file. Part of work for rdar://136303612.
