Draft: patches for native cross-compilation

When combined with pmbootstrap!2474 (merged) this allows for some packages to be built with abuild and the build tooling (e.g. meson) running on the native chroot rather than through QEMU, this drastically speeds up compilation.

When cross compiling, the makedepends should be split up into makedepends_host and makedepends_build. The build dependencies are those like "meson", build tools that we want to install and run on the native chroot. The host dependencies, are libraries, headers, etc for the architecture we're targeting. This follows the same semantics as Meson.

I've adjusted pmbootstrap to support these, and fall back by installing all makedepends in both chroots (which obviously isn't ideal).

Sorry to bother you @caleb,

but we've detected that this merge request hasn't seen any recent activity. If you need help, want to discuss your approach with developers, or you are all done and this is waiting for review, you can ping @postmarketOS. You can also ask on matrix in #devel:postmarketos.org or #postmarketos-devel on OFTC.

Thanks for your contribution.

This needs to be overhauled, for example pmb:cross-native -> pmb:cross-kernel rename has been removed in pmbootstrap!2474 (merged) and instead the new option is called pmb:cross-native2.

How about adjusting only a few packages like postmarketos-mkinitfs, unl0kr, ... first in this MR to use pmb:cross-native2 and then adjust more in follow-up MRs?
