[Dependency Scanning] Make GlobalModuleDependenciesCache aware of the current scanning action's target triple

And only resolve cached dependencies that came from scanning actions with the same target triple.

This change means that the `GlobalModuleDependenciesCache` must be configured with a specific target triple for every scannig action, and it will only resolve previously-found dependencies from previous scannig actions using the exact same triple.

Furthermore, the `GlobalModuleDependenciesCache` separately tracks source-file-based module dependencies as those represent main Swift modules of previous scanning actions, and we must be able to resolve those regardless of the target triple.
