Disable Jenkins Innerloop Jobs (#23287)

* Disable Jenkins Innerloop Jobs

This change will:

1) Remove default PR trigger jobs from being run in jenkins
2) Start submitting tests for linux arm32 in coreclr-ci

It is worth noting that this change will not remove jobs from netci.groovy.
This is to say that it is still possible to trigger innerloop and outerloop
jobs in jenkins, they will just not be run automatically on each new PR.

Past this point coreclr-ci will be the only PR triggered jobs to appear in Coreclr.
To see test results, navigate to the coreclr-ci Azure Dev Ops page at:
https://dev.azure.com/dnceng/public/_build?definitionId=228 and view the build related to your PR.
There is a test tab which will report all test results.

* Address PR feedback

* Add queue to array syntax

* Do not create push trigger jobs
