databases/mysql80-{client, server}: Update to latest release 8.0.18

switch patch-files to mysql80-server to make it easy for maintain.

Bugfix:
- CMake now enables use of fastcov if it is available. fastcov is faster than lcov or gcov. This requires GCC and gcov versions of 9 or higher.
- The DISABLE_SHARED CMake option was unused and has been removed.
- The CMake code to find Protobuf executables now works on platforms that split these into multiple packages.
- The new ADD_GDB_INDEX CMake option determines whether to enable generation of a .gdb_index section in binaries, which makes loading them in a debugger faster. The option is disabled by default. It has no effect if a linker other than lld or GNU gold is used.
- For the INSTALL_LAYOUT CMake option, the SLES and WIN option values were not used and have been removed.
- The max_prepared_stmt_count system variable maximum value has been increased from 1 million (1,048,576) to 4 million (4,194,304). The default value remains unchanged at 16,382.
- MySQL 8.0 no longer supports building using wolfSSL. All MySQL builds now use OpenSSL.
- The RE2 library is no longer used by MySQL. The library is no longer bundled with source distributions and the WITH_RE2 CMake option is obsolete.
