Add an annotation for @SkipMainlinePresubmit

This will typically be used in mainline-presubmit TEST_MAPPING
configuration to exclude some tests.

This is necessary as some tests are flaky in mainline configurations
(when running on older devices), and they need to be disabled to meet
SLO requirements, but they are not flaky on presubmit using the latest
platform builds.
