Build/Test Tools: Change 6.3 default values of LOCAL_PHP/`LOCAL_DB_…

…VERSION`.

This changes the default values for `LOCAL_PHP` and `LOCAL_DB_VERSION` in the 6.3 branch from `latest` to `8.2-fpm` (with beta support) and `5.7`, respectively, to properly reflect the highest versions of PHP and MySQL that this branch will support.

See #61533.
