Yes! I've wanted this for a long time!

Is this already possible?

We fixed the test concurrency recently. But I don't believe we fixed yet that the tests have 0 output if they pass? Or did we? I don't remember if we had other open issues why merging doesn't work yet. We should have a github issue somewhere.

What about merging the CI workflows? The ffigen and objective_c tests should be taken into account in tools/ci.dart (ditto for formatting, analyzing etc.)

[goderbauer]

I am still iterating over this to see what the remaining blockers are. I only found #1223, which didn't seem document any remaining issues... Stay tuned!

Note to future self:

• something is still broken with running ffigen and objective-c tests on macos in the native workflow
• Need to clean up the ffigen and objective_c workflows (some of their stuff is now performed by the native workflow)
• (likely unrelated to this PR): tests for native_toolchain_c are failing on MacOS and coverage upload is failing across platforms.
