GHA: C++11 testing and compiler name

Show compiler name (directly from inputs rather than from 'desc'.
Fix testing of C++11, C++14.
Allow for CSTD override to override with -std=gnu11 for languages
whose headers are not -std=c11 compatible.
Show c/c++ std being tested from github yaml file in the name.
