kconfig: Update all declared targets

Currently qconf-cfg.sh is the only script that touches the "-bin"
target, even though all of the conf_cfg rules declare that they do.
Make the recipe unconditionally touch all declared targets to avoid
incompatibilities with upcoming versions of GNU make:
https://lists.gnu.org/archive/html/info-gnu/2022-10/msg00008.html

e.g.
scripts/kconfig/Makefile:215: warning: pattern recipe did not update peer target 'scripts/kconfig/nconf-bin'.
scripts/kconfig/Makefile:215: warning: pattern recipe did not update peer target 'scripts/kconfig/mconf-bin'.
scripts/kconfig/Makefile:215: warning: pattern recipe did not update peer target 'scripts/kconfig/gconf-bin'.

kconfig: refactor .gitignore

Add '/' prefix to clarify that the generated files exist right under
scripts/kconfig/, but not in any sub-directory.

Replace '*conf-cfg' with '[gmnq]conf-cfg' to make it explicit, and
still short enough.

Use '[gmnq]conf' to combine gconf, mconf, nconf, and qconf.

kconfig: qconf: compile moc object separately

Currently, qconf.moc is included from qconf.cc but they can be compiled
independently.

When you modify qconf.cc, qconf.moc does not need recompiling.

Rename qconf.moc to qconf-moc.cc, and split it out as an independent
compilation unit.

.gitignore: remove too obvious comments

Some .gitignore files have comments like "Generated files",

kconfig: drop localization support

The localization support is broken and appears unused.
There is no google hits on the update-po-config target.
And there is no recent (5 years) activity related to the localization.

So lets just drop this as it is no longer used.

kconfig: remove 'config*' pattern from .gitignnore

I could not figure out why this pattern should be ignored.
Checking commit 1e65174a3378 ("Add some basic .gitignore files")
did not help.

Let's remove this pattern, then see if it is really needed.

Remove gperf usage from toolchain

It turns out that gperf-3.1 changed types in the generated code in ways
that aren't even trivially detectable without having to generate a test-file.

It's just not worth using tools and libraries from clowns that don't
understand or care about compatibility. So get rid of gperf.
