[pve-devel] [PATCH pve-kernel-meta/pve-installer] improve boot-mode switching

This patchset is the result from the discussion on the rfc for using grub as
only boot loader [0].

The patches for pve-kernel-meta are based on top of the v3 of the
`pin/unpin` addition [1].

The patches for pve-installer are independent from the pve-kernel-meta ones
(my tests used the current PVE 7.1 ISO w/o updating the pve-kernel-helper
package) - but I still consider them linked.

changes from the rfc:
* instead of using grub everywhere - we now use systemd-boot always for efi
  systems and leave grub only for legacy booted systems
* instead of unconditionally installing the boot-loaders for both modes on
  all ESPs users now can opt-in to installing the boot-loader for the other
  bootmode (both are updated if their configs are present, by default we
  only install the boot-loader for the current boot mode)

Tested the pve-kernel-meta with 3 VMs (ZFS+uefi, ZFS+legacy, ext4+uefi) and
switching boot-modes (after the necessary preparations).
Tested the pve-installer by scping proxinstall into a VM and installing
on btrfs+uefi, ext4+uefi, btrfs+legacy
