build: scripts/config - update to kconfig-v5.6

Browse Source 
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 dcf3e63a35 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

These files were taken from the Linux 3.9 Kernel
Configuration System and modified for the OpenWrt Buildroot.
These files were taken from the Linux Kernel Configuration System at commit
089b7d890f972f6b649fedc9259f6b93a18fb970 (Feb 4, 2020) and modified for the
OpenWrt Buildroot:
- Removed nconf, gconf, tests and kernel configuration targets.
- Adjusted the Makefile to compile outside the kernel.
- Always use default file when running make all{no,mod,yes}config.
- Added a 'reset' command to reset config when the target changes.
- Allow config reading from & writing to a different file.
- Allow 'source' command to use globs to include multiple files.
- Don't warn when selecting a symbol with unmet direct dependencies.
- Don't write auto.conf and other files under include/ directory.
- Reverted a commit to allow use of '/' & '.' in unquoted config symbols.
There are too many of those in OpenWrt right now.
- Reverted a commit that was issuing a warning when there were more than
one help text. This is used in a few packages to use different texts
for the menuconfig help, and the ipkg package description.
- Reverted an upstream change that avoids writing symbols that are not
visible to .config, which breaks OpenWrt busybox's '.config' generation
logic.
- Treat recursive dependency as a warning only; add a --fatalrecursive
option to conf to treat recursive deps as a fatal error.
- Use pre-built *.lex.c *.tab.[ch] files by default, to avoid depending on
flex & bison. Rebuild/remove these files only if running make with
BUILD_SHIPPED_FILES defined
