UPSTREAM: gcov: docs: add a note on GCC vs Clang differences

Document some things of note to gcov users:
1. GCC gcov and Clang llvm-cov tools are not compatible.
2. The use of GCC vs Clang is transparent at build-time.

Also adjust the documentation to account for the removal of config symbol
CONFIG_GCOV_FORMAT_AUTODETECT by commit 6a61b70b ("gcov: remove
CONFIG_GCOV_FORMAT_AUTODETECT").
