CI: Set explicit job names for matrix strategy workflows

By default, matrix jobs generate a name for themselves by concatenating
their job name and all matrix variables into a big string. Changing the
runner labels causes the job name to change, which means we need to go
into GitHub and change the required checks since those are name-based.

Give all matrix workflows an explicit, more stable name.
