* global_menu: check filesystem and bootloader compatibility

Before on install, only missing configurations were checked. This commit
introduces bootloader validatity checks on install which verify if the
selected filesystem is compatiable with the selected bootloader (for
example, it is not possible to boot limine from BTRFS).
