989a40cb - [clang][modules] Invalidate module cache when SDKSettings.json changes (#139751)

[clang][modules] Invalidate module cache when SDKSettings.json changes (#139751) This PR adds the `%sdk/SDKSettings.json` file to the PCM input file table, so that the PCM gets invalidated when the file changes. This is necessary for availability checks to work correctly.
