[release/5.0] Capture AVX context when redirecting threads for suspension

[VSadov]

Re: #38974, #47016

These are the same changes as in #47212

Customer Impact

Once we move to the new toolset, managed code that employs AVX register set directly or indirectly (as in Span<byte> helpers) may occasionally observe incorrect computation results.

Testing

The fix was tested and merged in master. This is a port of the fix.

Risk

Master branch had this fix for some time now. Based on that the risk is low.

I couldn't figure out the best area label to add to this PR. If you have write-permissions please help me learn by adding exactly one area label.

I had to port this by hand since files have been moved and there was enough code changes to prevent automated porting or cherry-picking.
Otherwise it was a straightforward port. We did not have any real changes affecting how we work with OS context prior to this fix.
