Add m1n1-aurora and the silent uboot-asahi for Apple Silicon, aarch64 and edge only

Ported from the asahi-quattro lane. Both are pinned by hand like
linux-aurora and restricted to aarch64 and the edge channel from their
first merge, since merging publishes. pkgrel sits one above the fork
lanes' builds so the same filename never carries two sets of bytes.
