CI: Add Julia 1.7 jobs

[jpsamaroo]

Extend AMDGPU job timeout to 3 hours Make AMDGPU job success mandatory

[jpsamaroo]

Need to update AMDGPU to support GPUCompiler 0.14 and remove oneAPI 1.7 job.

Yeah the oneAPI machine at MIT has been down for weeks... (cc @vchuravy) I'm hoping to replace it with one I manage, but there's bugs in the Intel compiler on that platform...

oneAPI bot is back, so its 1.7 CI job can be re-enabled.

[vchuravy]

@jpsamaroo Can you revert 672edb5

[maleadt]

Maybe rebase for Enzyme?

[maleadt]

This seems stale, and has conflicts with master. Better start with a new PR once we upgrade CI?
