Rework Cross Compile Type

This is a draft, because it breaks cross-native2 while initializing chroots somehow, I need to look into it another day - or maybe somebody else is interested in picking this up?

reproduce:

checkout pmaports!6297 (merged) to have postmarketos-mkinitfs use cross-native2
try to build it for a foreign arch

fails with:

Making this an enum seems reasonable to me!

I've reworded the MR and fixed the bug it had earlier. Locally it now passes these:

# unnecessary
pmbootstrap build hello-world --force

# crossdirect
pmbootstrap build hello-world --arch=aarch64 --force

# cross-native
pmbootstrap build arch-bin-masquerade --arch=aarch64 --force

# cross-native2
pmbootstrap build postmarketos-mkinitfs --arch=aarch64 --force

# qemu-only
pmbootstrap --no-cross build hello-world --arch=aarch64 --force

CI just failed for an unrelated reason postmarketos#101 (closed). CI should of course pass, but this can already be reviewed (maybe re-trigger it if it fails again).
