feat: build Sidero for amd64 and arm64, support arm64 in the agent

Use Talos tools for the build, upgrade protobuf/grpc.

Build images for both amd64 and arm64, and include assets
for both amd64 and arm64 (iPXE, kernel/initramfs for the agent).

Sideo picks up the right image based on the arch as reported by the
iPXE. iPXE correct version should be picked up by the DHCP server.
