Comment blocks for menus are great for dotconfig readability, but
currently it's the only type (beside plain comments) of submenus
for which these block are generated.
This series expands the code to also generate such blocks for choices
and menuconfigs and additionally expands the comments themselves a
bit to let know if they belong to choice or menu{,config} block.
Alexander Lobakin (2):
kconfig: fence choices and menuconfigs with comments in .config too
kconfig: mention submenu type in comment blocks in .config

To have a better understanding of the dotconfig blocks, mention if
a particular block-commented section is a choice or a menu{,config}.
Before:
CONFIG_TICK_ONESHOT=y
CONFIG_NO_HZ_COMMON=y
CONFIG_NO_HZ_IDLE=y
CONFIG_HIGH_RES_TIMERS=y
After:
CONFIG_TICK_ONESHOT=y

Comment blocks are now generated in .config only for menus. Provide
them for choices and menuconfigs too to greatly improve dotconfig
readability.
Choices before:
CONFIG_CC_OPTIMIZE_FOR_PERFORMANCE=y

Choices after:
CONFIG_CC_OPTIMIZE_FOR_PERFORMANCE=y
