misc/mei: Allow building standalone for compile testing
...
While this is not a particularly useful configuration, the MEI code should
compile even when no drivers for a GPU containing a management engine are
built.

misc/mei: Decouple ME interfaces from GPU drivers
...
These are enumerated via an auxiliary bus, so there is no functional
dependency between these drivers, therefore allow compiling MEI as builtin
even when i915/xe are built as modules.

mei: rework Kconfig dependencies
...
The dependencies in the mei framework are inconsistent, with some symbols
using 'select INTEL_MEI' to force it being enabled and others using
'depends on INTEL_MEI'.
In general, one should not select user-visible symbols, so change all
of these to normal dependencies, but change the default on INTEL_MEI to
be enabled when building a kernel for an Intel CPU with ME or a generic
x86 kernel.
Having consistent dependencies makes the 'menuconfig' listing more
readable by using proper indentation.
A large if/endif block is just a simpler syntax than repeating the
dependencies for each symbol.
