[libmysql] Fix for missing "ADD_COMPILE_FLAGS" command (#10162)

* [libmysql] Apply patch to prevent configuration error in extra/re2

Configuration of the embedded extra/re2 produces an error on Mac with Clang:

    CMake Error at extra/re2/CMakeLists.txt:74 (ADD_COMPILE_FLAGS):
      Unknown CMake command "ADD_COMPILE_FLAGS".

cmake/compile_flags.cmake was not included.

* [libmysql] Remove empty directory /lib/plugin/debug after installation

* [libmysql] Update version to 8.0.4-6

* [libmysql] Remove deprecated include(vcpkg_common_functions)

* [libmysql] x64-osx is now expected to pass CI

* [libmysql] Simplify copying of copyright file

* [libmysql] Handle unsupported triplets with vcpkg_fail_port_install
