[release/7.0] Update MsQuic to 2.1.1

[wfurt]

This is manual port of #75287, #75291, #75380 and #75534 to pick up MsQuic 2.1.1
(fixes#75262)

Customer Impact

as product change this impacts only Windows as we do not include MsQuic on Unix.
MsQuic 2.1.1 is bug fix releases and for .NET it is mostly needed for ARM64 on Linux.
The actual impact on Windows is small and it is mostly for consistently and to stay on top of stable msquic updates.
Also we will consume bits built and signed by MsQuic on all Windows architectures now. (we used out bits for x86 & x64 before)

The test only part updates Helix images so we can execute tests on various Linux distributions.

Testing

testing covered by runtime tests in main branch.

Risk

small

[wfurt]

please let me know if you have any concerns or if you approve it for 7.0 @danmoseley

Approved - we already discussed offline, this brings us into a consistent state.

[carlossanlop]

FYI - removing the servicing-consider label. The only requirements are a code review sign off ✔️, an M2 approval, ✔️, and a green CI 🔃.

From PR #75291 we are missing:

• Lines 46 & 48 -- Debian 10 & 11 arm64 -- the lines do not exist in 7.0, that is fine, we added them later I assume
• Line 84 - Debian.10.Amd64
• Line 88 - Debian.10.Amd64

Addressed in follow up commit fad7d09

[karelz]

LGTM, thanks!
@danmoseley it is ready for your approval -- oh, you already approved it above

[wfurt]

#75545 opened for tracking missing test.

[carlossanlop]

All infra changes. LGTM.

@wfurt@karelz@rzikm can you take a look at the failures? There's one in Quic.

No output, no crash or message about hanging test.
I don't think we have seen anything like this on main.
I will kick re-run....

@wfurt can you cherry-pick this change as well? so we have updated OpenSUSE as well:
#75534

[wfurt]

all tests are clean @carlossanlop

Approved, signed off, CI green. Ready to merge.
