Kbuild updates for v4.20 (2nd)

- clean-up leftovers in Kconfig files

- remove stale oldnoconfig and silentoldconfig targets

- remove unneeded cc-fullversion and cc-name variables

- improve merge_config script to allow overriding option prefix
kbuild: remove cc-name variable

There is one more user of $(cc-name) in the top Makefile. It is supposed
to detect Clang before invoking Kconfig, so it should still be there
in the $(shell ...) form. All the other users of $(cc-name) have been
replaced with $(CONFIG_CC_IS_CLANG). Hence, scripts/Kbuild.include does
not need to define cc-name any more.
