Roadmap v4 / PHPUnit 12

[jrfnl]

PHPUnit 12 is expected to be released on February 7.

As this is a major release with breaking changes, upgrading should be a done deliberately and managed.
This effectively means that upgrading to a PHPUnit Polyfills version which supports PHPUnit 12 should also be done deliberately and managed, so the Polyfills should get a new major release.

The intention is for the 1.x, 2.x and 3.x series to continue to be maintained, for as long as PHPUnit continues to make PHPUnit 9.x/10.x/11.x compatible with new PHP versions.
