chore: Bump rules_testing to 0.4.0 from 0.0.5 (#1306)

This uses the 0.4.0 release of rules_python, which has several features
we can make use of
 * Various internal APIs have been made public
 * target_compatible_with can be set to skip tests by platform
 * Unit tests are easier to write

Also adds rules_license 0.0.7, which is a dependency of rules_testing.

Work towards #1297
