[Test] Collapse mono runtime tests into single builds using global-build-job template

[naricc]

I am reviving this PR from a while ago.

This PR changes the way mono is build and consumed for runtime test lanes. Instead of separate steps that build and publish artifacts, and other steps that download them, building and running will be done on one machine.

This reduces the number of network connections required run the tests, and each of those is a potential source of failure. It does preclude the ability to share some build artifacts, but mono builds are fast.

It also lets use remove the coreclr dependency on the effected mono lanes.

There were a few tests that didn't run successfully with out the coreclr build for different reasons; I have excluded them in issues.targets for now and will investigate them individually as a follow up item.

mono-windows is still using the old path while I investigate some errors in the build.cmd script.

Contributes to: #45521

This PR only changes the ones in the runtime pipeline. Follow up PRs will change runtime-staging.
