Rollup merge of #54964 - tromey:run-both-gdb-and-lldb-tests, r=nikomatsakis

Browse source 
Run both lldb and gdb tests

Currently lldb tests are run only on macOS, and gdb tests are only run
elsewhere.  This patch changes this to run tests depending on what is
available.

One test is changed, as it was previously marked as failing on macOS,
whereas really it is a generic failure with lldb.

Closes #54721
