ci: Split to multiple workflows

- build: build on multiple version of macOS
- lima: lima integration tests
- qemu: lima integration tests
- release: already exist

Try to run integration tests on all platforms to see what works now.  We
probably want to minimize the number of platform since the macOS runners
are very flaky.

The lima workflow is flaky. Sometimes all 3 platforms succeed, but
usually one gets stuck and cancelled after many minutes.

Notes:
- Workflow names unified to Title case. This is more consistent with
  github UI and standard workflow names.

Workarounds:
- on macos-15-large brew is not updated and get lima 0.23.2. Fixed by
  running brew update.
