349de028 - [clang][Modules] Refactor modulemap lookup & parse functions, NFCI

[clang][Modules] Refactor modulemap lookup & parse functions, NFCI * Split `lookupModule` into seperable functions to isolate parsing from loading of a module. * Do the same for `parseAndLoadModuleMapFile` functionality. * Clarify related docstrings. This is in effort to lookup modules without ever loading the full module definition, which will be introduced in a follow up patch leveraging lazy module map searching.
