A Mono counterpart to a new feature already implemented in CoreCLR and NativeAOT. Missed RC snap.

• No

[If yes, specify when the regression was introduced. Provide the PR or commit if known.]

blocking merge to investigate possible issue (#118981)

That was because couple tests were not supposed to run with llvmaotfull. Added a fix from main to this PR.

The failure does not seem to be related to finalizers.

The errors are the same as without this change (ex: https://dev.azure.com/dnceng-public/public/_build/results?buildId=1134198&view=ms.vss-test-web.build-test-results-tab)

I think we can merge this.

[VSadov]

I do not have permissions to merge though . . .

[mangod9]

@jeffschwMSFT should be able to merge.
