Subject: [PATCH] Build/Test Tools: Avoid running full PHPUnit test suite for
 every PHP file change.

Use `grunt watch --phpunit --group={testgroup}` to start `grunt watch` with a specific test group so that PHP file changes trigger a limited number of tests.

Props jeremyfelt, birgire for testing.
Fixes #44240.
