Merge bitcoin/bitcoin#28187: ci: Run "macOS native x86_64" job on GitHub Actions

9658d0d ci: Run "macOS native x86_64" job on GitHub Actions (Hennadii Stepanov)

Pull request description:

  From bitcoin/bitcoin#28098:
  > Thus, someone would have to sponsor an amount of roughly 5kUSD/mo for those two tasks.

  > If the goal is to stay on a free plan, I think the only option is GitHub Actions CI.

  **IMPORTANT NOTE**. We currently ship macOS release binaries for both architectures: `x86_64` and `arm64`. If this PR gets merged, only `x86_64` architecture will be tested on CI, which implies some [drawbacks](bitcoin/bitcoin#28187 (comment)).

  However, it has never been the case that our CI tested both architectures simultaneously. And we hope that GitHub Actions will soon host macOS `arm64` runners.

  Historically, we moved from `x86_64` to `arm64` in bitcoin/bitcoin#26388 less than a year ago.
