As the display API now check against valid callback functions and
returns -ENOSYS (or equalent), there is no need to provide
such functions in the driver code

With the incoming removal of kernel.h/types.h from init.h, lots of files
start to show compile errors because they relied on indirect
definitions, including errno.h.

Convert the device to be Devicetree based. Adjusted tests and other
areas that were using old Kconfig properties.

config/data accessors have been removed from all (or most) in-tree
drivers, do the same here.

The "framebuf" driver was an incomplete driver expecting _clients_ to
implement missing functionality (i.e. init and device definition)
outside of the driver. This pattern of scattering driver code throughout
the tree is not common (if used at all). If certain drivers share
functionality, one can create a common module within the subsystem (see
e.g. ILI9XXX drivers).
The _generic_ framebuffer code was only used to implement the Intel
Multiboot framebuffer driver. This patch centralizes all the scattered
code in the subsystem and adjusts the driver name to "intel_multibootfb"
to make things clear. If there's ever another framebuffer driver that
shares code, it can be split into multiple modules.

In order to bring consistency in-tree, migrate all drivers to the new
prefix <zephyr/...>. Note that the conversion has been scripted, refer
to #45388 for more details.

move display.h to drivers/display.h and
create a shim for backward-compatibility.
No functional changes to the headers.
A warning in the shim can be controlled with CONFIG_COMPAT_INCLUDES.

A basic display driver is added for a generic 32-bpp framebuffer.
Glue logic is added to the x86 arch to request the intitialization
of a linear framebuffer by the Multiboot loader (GRUB) and connect
it to this generic driver.
