The remote builder was hardcoded to use --platform linux/amd64
regardless of user input or runner architecture. This caused
performance issues on ARM runners and cache inefficiencies.
Now properly uses the platforms input or detects host architecture
to avoid unnecessary QEMU emulation and improve build performance.

This setup-only mode will setup a docker builder with the stickydisk
mounted but will not run a Docker build. The use case here is to allow
customers to then run their custom Tilt files or Docker commands against
our builder. The other subtle change is that we only cleanup in the post
step of this builder action. It is still to be seen if you can start several
of these builders at the same time in a workflow but we can do that as a follow
on.
