  [KeyInstr][Clang] Reset atomGroup number for each function (#141607)

CGDebugInfo::completeFunction was added previously but mistakenly not
called (dropped through the cracks while putting together the patch
stack). Moved out of #134652 and #134654.

This patch is part of a stack that teaches Clang to generate Key Instructions
metadata for C and C++.

RFC:
https://discourse.llvm.org/t/rfc-improving-is-stmt-placement-for-better-interactive-debugging/82668

The feature is only functional in LLVM if LLVM is built with CMake flag
LLVM_EXPERIMENTAL_KEY_INSTRUCTIONs. Eventually that flag will be removed.
