all: replace linux-arm64-aws with linux-arm64

This change replaces linux-arm64-aws with linux-arm64. The new builder runs
on GCP and has an increased set of resources. This should provide a
performance improvement.

The builder will now be used:
- To release linux-arm64
- As the linux-arm64 trybot

Fixes golang/go#53851
Updates golang/go#54679
Updates golang/go#40561
