This PR does the following: - Updates the base docker image used by the manylinux2014_aarch64 artifact build from a dockcross image that uses cross-compilation to a simple pypa image that doesn't require cross-compilation - Hence switch the manylinux2014_aarch64 build to run in an ARM64 machine without cross compiling. - We already have a '**Distribution Tests Python Linux Arm64**' job that runs on an ARM64 machine to build only `musllinux_aarch64` targets. - Updating the build process so that the manylinux2014_aarch64 target is also now built as part of the '**Distribution Tests Python Linux Arm64**' job instead of the '**Distribution Tests Python Linux**' job. This change cuts the execution time of the '**Distribution Tests Python Linux**' job significantly effectively reducing the total runtime by over 55% as shown below: - Previously the presubmit runs usually take about 75-90 minutes of runtime: [Example run from grpc#40317](https://btx.cloud.google.com/invocations/147e002e-12da-441f-a744-630233725563/targets) - Now the presubmit run-time has reduced to about 30-40 minutes: [Test run from this PR](https://btx.cloud.google.com/invocations/93602c73-228b-48e1-9bcc-059f51479887/targets) Given that the presubmit jobs building only a small subset of targets show such time improvement, the release job which currently builds many more aarch64 artifacts will also show significant execution time improvement going forward.
