Add TextRange::Contains tests spanning base/extent (#21874)

Browse Source 
Adds tests for TextRange::Contains(const TextRange&) where the range
being tested spans the base/extent of the testing range.

This was originally intended to land in #21854, but it seems I didn't
push the additional tests before landing.
