build: scripts/config - update to kconfig-v5.6
Major changes include:
- Much more readable reverse dependencies separated in groups
- Improved recursive dependency report
- More readable .config files: add comments to signal end of menus
- More warnings for incorrect Config.in entries, such as a 'choice'
default not contained in the 'choice'
- Hability to properly display pseudographics with non-latin locales
- Recursive dependencies can optionally be treated as errors
Changes from failed dcf3e63a35d05e7e5103819c0f17195bfafe9baa attempt:
- Recursive dependencies are treated as warnings by default
- The option to treat them as errors is implemented as a command-line
flag to scripts/config/conf instead of a compile-time definition
- fixed handling of select with umnet dependencies
