  [clang][deps] NFC: Stop assuming the TU's context hash

The context hash of modular dependencies can be different from the context hash of the original translation unit if we modify their `CompilerInvocation`s.

Stop assuming the TU's context hash everywhere.

No functionality change here, since we're still currently using the unmodified TU CompilerInvocation to compute the context hash.
