Xi Ge 8fa2e8a03d ModuleLoader: teach canImport to check Swift user module versions ...

For config condition `canImport(Foo, version: N)`, this patch teaches the compiler to check N
against the version of the Swift module Foo on disk. It returns true if the module version on
disk is greater or equal to N and returns false otherwise.
