mm/slab: rename CONFIG_SLAB to CONFIG_SLAB_DEPRECATED

As discussed at LSF/MM [1] [2] and with no objections raised there,
deprecate the SLAB allocator. Rename the user-visible option so that
users with CONFIG_SLAB=y get a new prompt with explanation during make
oldconfig, while make olddefconfig will just switch to SLUB.

In all defconfigs with CONFIG_SLAB=y remove the line so those also
switch to SLUB. Regressions due to the switch should be reported to
linux-mm and slab maintainers.

kernels, so let's reflect that in the 32-bit ARM defconfigs.

ARM: defconfig: address renamed CONFIG_DEBUG_INFO=y

CONFIG_DEBUG_INFO is now implicitly selected if one picks one of the
explicit options that could be DEBUG_INFO_DWARF_TOOLCHAIN_DEFAULT,
DEBUG_INFO_DWARF4, DEBUG_INFO_DWARF5.

This was actually not what I had in mind when I suggested making
it a 'choice' statement, but it's too late to change again now,
and the Kconfig logic is more sensible in the new form.

Change any defconfig file that had CONFIG_DEBUG_INFO enabled
but did not pick DWARF4 or DWARF5 explicitly to now pick the toolchain
default.

ARM: refresh defconfig files

A lot of Kconfig options have changed over the years, and we tend
to not do a blind 'make defconfig' to refresh the files, to ensure
we catch options that should not have gone away.

I used some a bit of scripting to only rework the bits where an
option moved around in any of the defconfig files, without also
dropping any of the other lines, to make it clearer which options
we no longer have.
