feat: migrate global unit tests from Mocha to Jest

[itsyoboieltr]

Description

This PR converts the global unit tests from Mocha to Jest. It removes the test-unit-global CircleCI pipeline and runs the global unit tests on GitHub actions along with the normal unit tests, contributing to the coverage report.

Upon discussion with @Gudahtt the ignored dysfunctional unit test test/unit-global/protect-intrinsics.test.js which was not compatible with the Jest environment will be re-introduced in a separate PR. The test will be ported to run as part of the e2e test suite, as the browser would be a better test environment, closer to production.

Fixes: #25496

Manual testing steps

1. Tests should be in Jest syntax, and should still pass
2. Tests should run on GitHub actions with normal unit tests, not on CircleCI
