Support exposing the contents of module maps created by CMake to LSP engines.

Debug Log

Additional Information

CMake creates module map files which holds module mapping of translation units to used module files on disk. This information should be exposed to LSP engines without user intervention as examplified here @bobbrow mentioned that this part of the integration is the onus of CMakeTools, not CppTools.

Thanks for the issue, I've placed it in our backlog and we will prioritize it when we can based on bandwidth and demand for other issues. Thanks!
