Superpmi collection pipeline improvements (#49385)

Superpmi collection pipeline improvements (#49385)

* Do not pass --use-zapdisable to dotnet

But instead pass to individual CoreRun.exe that is launched during benchmark run. That way we do not slow down the launch of dotnet.exe process.

* Fail superpmi collection pipeline if there was no valid .mch files were found to merge

* Upload merged .mch files as zipped artifacts

TODO: Upload the superpmi.log from all the partition runs

* TEMP: New Jit guid

- Add new JIT guid so we don't overwrite the existing .mch files
- Disable all the runs except benchmarks

* add trailing path sep

* Upload superpmi.logs separately

* Use PublishPipelineArtifacts instead of upload artifacts

* properly pass zapdisable to CoreRun.exe

* Revert "TEMP: New Jit guid"

This reverts commit e89ef69625e4e57bb622fc35ff66d82f14b34285.

* Remove CoreClrTestBuildHost from benchmark run

* fix --envVars for benchmarks run

* add missing space

* temporary disable other runs

* Revert "temporary disable other runs"

This reverts commit 2926d1f582061eee6c7852046982ffb5107887b3.
