[Bug 1896755] [NEW] Backport snap-preseed work from groovy to focal

[Dimitri John Ledkov]

Public bug reported:

[Impact]

 * livecd-rootfs when building classic images with snaps preseeded
doesn't perform any first-boot tasks during image building. It means
fist boot is computationally intensive. In groovy, livecd-rootfs gained
ability to precompute snap seeding, apparmor profiles making first boot
snap seeding a lot faster. Backport the goodies.

[Test Case]

 * Perform stock build of ubuntu-cpc lxd or qcow cloud image

 * Boot and observe they complete boot, and perfrom snap seeding very
quickly (i.e. less than a couple of seconds)

[Regression Potential]

 * Images might fail to build, or be missbuilt. However, these changes
have been tested on groovy with the same snapd across all SKUs. Thus
only groovy-vs-focal incompatibilities may arise.
