Split the unit/font tests into per-browser jobs

This commit mirrors the approach from e656b83 to the other workflows
that run multiple OS/browser combinations. This approach has multiple
advantages:

- it improves performance because each job is run in its own environment
  so we don't have two browsers competing for resources in the same
  environment anymore;
- it improves monitoring because each job is shown separately, with its
  own runtime, in e.g. the pull request checks and actions overviews,
  which makes it easier to spot bottlenecks that are specific to a
  certain OS/browser combination and enable follow-up optimizations.
