Boot splash starts too late to be useful - Use SimpleDRM by default

Bug description:
The boot splash and animations start too late to be useful.
Modern systems spend all their boot time (a couple of seconds)
decompressing the kernel. During that time the user only sees the
static BIOS logo (ACPI BGRT). Then when Plymouth can finally start
animating, the startup process is already finished and there's
virtually no time left to show any useful animations.
This could be fixed in:
grub: By adding a splash under the BIOS logo to show some progress
_before_ a Linux kernel is even started
and/or
plymouth: By preferencing legacy framebuffer devices (like EFI) over
DRM, if we find those are available a few seconds sooner. That would
also fix bug 1868240 completely, and bug 1836858 mostly as the flicker
moves to when the login screen starts.
