kconfig: update to Linux 5.13-rc1

The previous sync was Linux 5.9-rc2.

Resync scripts/kconfig/ with Linux 5.13-rc1.

Highlights:

 - make header names in include/config/ and CONFIG symbols match
   (scripts/basic/fixdep.c was adjusted)

 - remove all 'option' syntax
   (common/Kconfig was adjusted)

 - introduce KCONFIG_DEFCONFIG_LIST instead of 'option defconfig_list'

 - bug fixes and cleanups of nconfig

 - drop Qt4 support from xconfig

 - bug fixes, improvements, cleanups of xconfig

 - print a short log for syncconfig
