This has two big visible changes:
* `installer` image now contains assets for both `amd64` and `arm64`, so
it can be used to generate any Talos image (including RPi on amd64 host)
* Talos is using cross-compilation instead of emulation to build
non-native architectures: on amd64, Go amd64 compiler produces binaries
for both arm64 and amd64
(before this change: Go arm64 compiler via QEMU produces arm64 binaries on amd64)
CI implications: we no longer require arm64 nodes.
Changes walkthrough:
* `installer` container now keeps assets under `/usr/install/<arch>`
* Dockerfile build starts forcing toolchain/base image to use the build
host native architecture, not target architecture
* lots of duplication for amd64/arm64 as we want to combine assets for
both arches in a single image (e.g. we have multi-arch amd64/arm64
installer image, each arch has native installer binary, but both arches
contain full set of amd64/arm64 assets)
* fixed a small bug preventing arm64 on amd64 talosctl cluster create

This builds a bundle with CNI plugins for talosctl which is
automatically downloaded by `talosctl` if CNI plugins are missing.
CNI directories are moved by default to the `~/.talos/cni` path.
Also add a bunch of pre-flight checks to the QEMU provisioner to make it
easier to bootstrap the Talos QEMU cluster.
