PHP 8.0 | PSR2/PSR12/ControlStructureSpacing: check match expressions

This adds support for checking the spacing inside single line conditions for `match` expressions to the PSR2 sniff and by extension to the PSR12 sniff, as well as explicitly for multiline conditions to the PSR12 sniff.

Includes unit tests.
