[HttpStress] Consider adding a nightly HTTP/3.0 leg with standard Release MSQUIC build

[antonfirsov]

Besides enabling ASan, #100023 switched to DEBUG msquic, slowing down the runs 2x which which means timing characteristics of the SUT are now quite different. IMO we need to make sure we do stress test the same system as we deploy, therefore I recommend adding another leg to the nightly builds. @ManickaP @radkz @CarnaViire I leave it to you to triage, hopefully I will be able to contribute this change at some point, shouldn't be hard.

Triage: fine with me. We want results in reasonable time on PRs, but the nightly build can take a bit longer.
