Rename "GPU" macros to be explicitly for Ganesh backends.

Basically a big find/replace of DEF_GPUTEST -> DEF_GANESH_TEST

Then I ran git clang-format <parent CL branch>. I had to install
the git-clang-format script, but it was worth it. I documented
how to install it in .clang-format.

Note some updated docs in TestTest.cpp
