Summary
As per CircleCI's announced deprecation the Mac AMD64 resource class is being deprecated. As a result we should disable these tests.
This PR also switches to using CircleCI's mac resources, instead of a self-hosted runner.
There is a larger question of how much support we should provide to Intel architecture in general. The last Intel mac was discontinued a year ago. A universal build like in #6023 would obviate the need for AMD64 build platforms and dealing with XCode deprecations, but would lead to insecurity about validity of tests.
Test Plan
Force nightly tests to execute against this branch.
Note: the test failure is from running the nightly execution, and the failure is unrelated to this change. It can be ignored.
