Add JIT stress mode testing using libraries tests (#36486)

* Add JIT stress mode testing using libraries tests

There are three separate pipelines, with different sets of JIT
stress modes enabled for each:

- libraries-jitstress.yml
- libraries-jitstress2-jitstressregs.yml
- libraries-jitstressregs.yml

The live built Release libraries are used with a Checked CoreCLR.

The non-stress configuration is tested during normal PR testing.

The libraries `sendtohelix.proj` file is changed to take an optional
list of CoreCLR stress scenarios to run. If given, a set of environment
setting scripts is created and added to the Helix correlation payload.
Then, an auxiliary `sendtohelixhelp.proj` file is invoked for each
scenario (or just the default, empty scenario) to create and run the
Helix tasks.

* Remove remnants of old corefx-on-coreclr test run infrastructure

* Rename corefx-*.yml to libraries-*.yml

* Disable tests
