[TASK] Avoid phpstan 'PHPDoc tag @var has invalid value' errors

Annotations are sometimes:
/** @var $foo MyType */
But should be:
/** @var MyType $foo */

The patch fixes this in all tests: getMock() and
createMock() need no annotation at all (both phpstan and
phpstorm understand this), getAccessibleMock() currently
needs an annotation and then sometimes mumbles about
obsolete arguments for _call(), which can be adapted
with another patch.

Resolves: #96692
Releases: main, 11.5
