Fixes build issue with LLVM on Windows with cmake (#10776)

Browse Source 
LLVM fails to build on Windows with C++ 20 standard.  When building LLVM
on Windows, we use C++ 14 already.  This commit changes the c++ standard
to be picked by each subdirectory rather than the standard being picked
by the root level cmake file.
