[BE] Enables support for pytorch ci build in ARC + introduces _linux-build-rg.yml. (#121930)
Introduce changes related to enable ARC to run on build for linux-jammy-py3.8-gcc11
Depends on:
* https://github.com/pytorch/pytorch/pull/121908
* https://github.com/pytorch/pytorch/pull/121907
* Force docker to update credentials: https://github.com/pytorch/test-infra/pull/4991
* Add permissions to role to access ECR: https://github.com/pytorch/ci-infra/commit/acc0154aa0289369411c2f3105a21ce6010a1da4
* Add permissions to the role to access relevant S3 bucket: https://github.com/pytorch/ci-infra/commit/496b0422c360fb5ca98b9de5db0e1d8f749b22cc
## Reasoning for introducing a new `_linux-build-rg.yml`
Old style `runs-on` definition accept a string, new style `runs-on` requires a object in the format:
```
--- old
...
runs-on: "linux.2xlarge"
...
--- new
...
runs-on:
group: "running-group"
...
```
In other words, to specify a group the format of the yaml needs to be changed. Unfortunately, there is no way to accomplish this change using any trick in the book that I am aware of. This is due to the fact that GH actions yaml are not templatable and support minimal functions / replacements. A few examples that did not work:
