dev-python/mysqlclient: add 2.0.3, enable py3.10 and tests

Also:
* Update licence to GPL-2+.
* Remove RST files from DOCS, they are included in HTML_DOCS.
* Bump to EAPI 8.
* Mask the test USE flag for riscv where dev-db/mariadb is not
  available.
* Remove reference to treecleaned dev-python/mysql-python.
