[Yamato] Use cache server for Yamato jobs

[sophiaaar]

Purpose of this PR

• Add a new test platform "playmode_cache"
• Changed project pipelines to use playmode_cache in their CI (regular playmode is still available to kick off)

TIming improvements examples:
HDRP Windows DX11 playmode on master - execution time: 1 hour 20 minutes
HDRP Windows DX11 playmode on cache server branch - execution time: 20 minutes

HDRP Windows Vulkan playmode on master - execution time: 1 hour 50 minutes
HDRP Windows Vulkan playmode on cache server branch - execution time: 50 minutes

Testing status

https://yamato.cds.internal.unity3d.com/jobs/902-Graphics/tree/yamato%252Fuse-cache-server

• re-ran several playmode_cache jobs to note the time go down

Comments to reviewers

• previously tested on the branch yamato/cache-server, but moved to this new branch for a cleaner PR and to use the new "extra utr args"
• Tried to enable cache server for builds but it didn't make a time difference (case id 1305607)
• Failures match master

Awesome!
Is there a recent nightly/ABV? I only see some that are 4 or 5 days old. Would love to see one for hdrp.

I wonder if

• keeping the same name (just playmode) for the playmode cache jobs and
• renaming the regular playmode jobs to playmode_no_cache

would make sense? That would allow us to keep the same unique names in yamato, and keep the run history.
Maybe that's too much rework for too little benefits though, only an idea.

this is a good point. my thought is that "no cache" has been the default for so long that i dont want to sneak in like a "hidden" change, but maybe that doesnt matter 🤔

havent ran full abv yet but here are some recent hdrp jobs:

• https://yamato.cds.internal.unity3d.com/jobs/902-Graphics/tree/yamato%252Fuse-cache-server/.yamato%252Fhdrp-win-dx11.yml%2523HDRP_Win_DX11_playmode_cache_mono_Linear_trunk
• https://yamato.cds.internal.unity3d.com/jobs/902-Graphics/tree/yamato%252Fuse-cache-server/.yamato%252Fhdrp_dxr-win-dx12.yml%2523HDRP_DXR_Win_DX12_playmode_cache_mono_Linear_trunk
• https://yamato.cds.internal.unity3d.com/jobs/902-Graphics/tree/yamato%252Fuse-cache-server/.yamato%252Fhdrp-win-dx12.yml%2523HDRP_Win_DX12_playmode_cache_mono_Linear_trunk
• https://yamato.cds.internal.unity3d.com/jobs/902-Graphics/tree/yamato%252Fuse-cache-server/.yamato%252Fhdrp-win-vulkan.yml%2523HDRP_Win_Vulkan_playmode_cache_mono_Linear_trunk

remember to look at execution time rather than the overall job time :) and always look at the most recent - the first runs do the upload to the cache server, so they will be similar timings to master (some are still running, sorry.)
