Support linux/arm64/v8 for most Ubuntu-based images (#1597)

Previously, many images only provided `linux/amd64` builds, which meant that Apple silicon folks were left to Rosetta or qemu emulation when cross-compiling. Although Rosetta's `x86_64` emulation is a remarkable feat of engineering, nothing beats the performance of using the `linux/arm64/v8` on Apple silicon. This PR adds support to a bunch of Ubuntu-based images for `linux/arm64/v8` builds. I haven't been able to build all of them yet... mostly just tested the `x86_64-unknown-linux-gnu` container. But I plan to squash any issues that arise from CI. Theoretically, it shouldn't be too hard since the core logic is the same across all images. ### New Platforms Supported - `aarch64-unknown-linux-gnu` - `armv5te-unknown-linux-gnueabi` - `armv7-unknown-linux-gnueabi` - `i586-unknown-linux-gnu` - `i686-unknown-linux-gnu` - `mips-unknown-linux-gnu` - `mips64-unknown-linux-gnuabi64` - `mips64el-unknown-linux-gnuabi64` - `mipsel-unknown-linux-gnu` - `powerpc-unknown-linux-gnu` - `powerpc64-unknown-linux-gnu` - `powerpc64le-unknown-linux-gnu` - `riscv64gc-unknown-linux-gnu` - `s390x-unknown-linux-gnu` - `sparc64-unknown-linux-gnu` - `thumbv7neon-unknown-linux-gnueabihf` - `x86_64-unknown-linux-gnu`
