8290000: Bump macOS GitHub actions to macOS 11

[gdams]

macOS 10.15 has been deprecated for some time and will be removed completely on August 30th. See https://github.com/actions/virtual-environments#available-environments and actions/runner-images#5583 for context.

It's also worth pointing out that they are shutting down the agents already which means that we likely see longer wait times for executors so this should speed up the workflow for developers. We'll need to backport this all the way down to JDK8u to avoid breaking the CI system.

@gdams Please do not rebase or force-push to an active PR as it invalidates existing review comments. All changes will be squashed into a single commit automatically when integrating. See OpenJDK Developers’ Guide for more information.

[gdams]

cc @erikj79 @magicus I think this PR likely needs one of you to review it? There is a reasonable sense of urgency here because I'm going to need to backport this down to all versions.

[shipilev]

Looks fine to me. XCode 11.7 is listed as the lowest version supported by macos-11 image.

[openjdk]

@gdams This change now passes all automated pre-integration checks.

ℹ️ This project also has non-automated pre-integration requirements. Please see the file CONTRIBUTING.md for details.

After integration, the commit message for the final commit will be:

Thanks for the review @shipilev! Are you willing to sponsor?

[openjdk]

@gdams
Your change (at version bbb2758) is now ready to be sponsored by a Committer.

[shipilev]

I shall wait for some more people to ack this, and then I can sponsor.

[RealCLanger]

I think this should be fine, reading the matrix at https://wiki.openjdk.org/display/Build/Supported+Build+Platforms and taking into account the deprecation of macos-10.15 as runner platform in Github Actions.

[shipilev]

All right then! I was thinking if we should do XCode 12.4 then, to align better with the matrix. But since this patch is targeted for backporting, it would probably be better to stick to the lowest toolchain version.
