[Modules] Resolve top-headers of modules lazily.
This allows resolving top-header filenames of modules to FileEntries when
we need them, not eagerly.
Note that that this breaks ABI for libclang functions
clang_Module_getTopLevelHeader / clang_Module_getNumTopLevelHeaders
but this is fine because they are experimental and not widely used yet.
