[5.10] Gate new tests on supportsSDKDependentTests()

[neonichu]

(cherry picked from commit 8bc47da)

• Explanation:

We have been seeing flakiness of tests requiring the SDK (e.g. compiling manifests or running tests) for quite some time on the smoke test macOS CI. Some new tests were recently added which fall under this category but haven't been marked with the appropriate skipping clauses.

• Scope: smoke test CI runs on macOS
• Risk: none, this is a test-only change
• Testing: this is a test-only change
• Reviewer: @bnbarham
• Main branch PR: Gate new tests on supportsSDKDependentTests() #7305

Hm, this doesn't look like flakiness to me? Potentially Windows CI doesn't work anymore for 5.10?
