[PassManager] Make PassManagerBuilder::addExtension take an std::function, rather than a function pointer.
Summary:
This gives callers flexibility to pass lambdas with captures, which lets
callers avoid the C-style void*-ptr closure style. (Currently, callers
in clang store state in the PassManagerBuilderBase arg.)
No functional change, and the new API is backwards-compatible.
