Rollup merge of rust-lang#117700 - Zalathar:rename-run-coverage, r=onur-ozkan

coverage: Rename the `run-coverage` test mode to `coverage-run`

Follow-up to rust-lang#117484 (comment).

Renaming this test mode to `coverage-run` makes it more consistent with the `coverage-map` mode and the shared `tests/coverage` test directory.

 These tests can be sensitive to small changes in MIR spans or MIR control flow,
 especially in HIR-to-MIR lowering or MIR optimizations.
 
 If you haven't touched the coverage code directly, and the tests still pass in
-`run-coverage` mode, then it should usually be OK to just re-bless the mappings
+`coverage-run` mode, then it should usually be OK to just re-bless the mappings
 as necessary with `./x.py test coverage-map --bless`, without worrying too much
 about the exact changes.
