It avoids the dependency on bison/flex, minimally speeds up the build
and also works around weird race conditions in some versions of bison
that need more investigation.
The issue this avoids manifests as a build error when creating
parser.tab.c:
input in flex scanner failed
make: *** [util/kconfig/Makefile.inc:66: build/util/kconfig/parser.tab.c] Error 2
Since the error happens within bison the alternative would be to make
bison part of our crossgcc environment to ensure that no broken OS
build is used.

With parser.tab.h depending on parser.tab.c it's possible for make
to initiate the creation of parser.tab.c, then try to compile it,
even though parser.tab.h is still missing.
This isn't normally an issue yet because bison creates them both at
a time but with pre-compiled files this will become a problem.
Pattern rules support (until recently as a special case that no other
type of rule could implement) multiple targets that are actually
treated as "one command creates multiple output files" so use that
to state the relationship properly.

Our documentation claims that the DEFCONFIG make variable, used for
targets such as savedefconfig, defaults to 'defconfig'.
With the update to kconfig 5.13 we lost this default, so bring it back.

This was originally several commits that had to be squashed into one
because the intermediate states weren't able to build coreboot:
- one to remove everything that wasn't our own code, leaving only
regex.[ch], toada.c, description.md and Makefile.inc.
- one to copy in Linux 5.13's scripts/kconfig and adapt Makefile.inc
to make the original Makefile work again.
- adapt abuild to use olddefconfig, simplifying matters.
- apply patches in util/kconfig/patches.
- Some more adaptations to the libpayload build system.
The patches are now in util/kconfig/patches/, reverse applying them
should lead to a util/kconfig/ tree that contains exactly the Linux
version + our own 5 files.
