 In #51423 several issues were identified with function argument types that
 were detected by PHPStan.

 There are other issues that PHPStan detects too such as potentially
 undefined variables, functions called with incorrect number of parameters,
 access to undefined properties, and more as you increase the level of
 checking performed.

 We can scan core using the level 1 checks and catch quite a few low
 hanging fruit, and then go from there.

 Follow-up task: Consider whether it's beneficial to add PHPStan (or Psalm
 or Phan) analysis to the build tooling and CI.
