Build/Test Tools: Add an input to allow errors for the PHPUnit workflow.

This allows a calling workflow to configure the PHPUnit workflow to `continue-on-error` when one occurs. This is useful for older branches where support for a specific version of PHP was not at 100% within the test suite.

Follow up to [58165], [58269], [58270], [58329].

See #61213.
