configs: drop GENERIC_PTDUMP from debug.config

Patch series "mm: Rework generic PTDUMP configs", v2.

The series reworks generic PTDUMP configs before eventually renaming them
after some basic clean ups first.  This is derived after splitting changes
from the following patch:
https://lore.kernel.org/all/20250205050039.1506377-1-anshuman.khandual@arm.com/

This patch (of 5):

The platforms that support GENERIC_PTDUMP select the config explicitly.
But enabling this feature on platforms that don't really support - does
nothing or might cause a build failure.  Hence just drop GENERIC_PTDUMP
from generic debug.config
