Subject: GHA: start using ARM Linux runners
X-Git-Tag: curl-8_12_0~99
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=911f003db8d0d75e0eaed05002c4b42ad3327ff4;p=thirdparty%2Fcurl.git

GHA: start using ARM Linux runners

- GHA/linux: allow per-job runner image override.
- GHA/linux: add an arm version of an existing job.
  Add workaround for broken `PATH` in the arm runner image.
- GHA/non-native: add CPU arch to job name where missing.
- GHA/checkdocs: switch a linter job to arm.

Performance looks a little bit better than Intel
(presumably with lower power consumption).

Test jobs, with openssl, tests, pytests, examples:
- arm:

  - https://github.com/curl/curl/actions/runs/12816201136/job/35736615144 4m5s
- Intel:
  - https://github.com/curl/curl/actions/runs/12816430794/job/35737374118 4m32s
  - https://github.com/curl/curl/actions/runs/12816201136/job/35736614764 4m13s
