Rollup merge of #110823 - compiler-errors:tweak-await-span, r=b-naber

Tweak await span to not contain dot

Fixes a discrepancy between method calls and await expressions where the latter are desugared to have a span that *contains* the dot (i.e. `.await`) but method call identifiers don't contain the dot. This leads to weird suggestions suggestions in borrowck -- see linked issue.

Fixes #110761

This mostly touches a bunch of tests to tighten their `await` span.
