Subject: [PATCH v2] kconfig: menuconfig: Make hidden options show with different color
When hidden options are toggled on (using 'z'), the number of options
on the screen can be overwhelming and may make it hard to distinguish
between available and hidden ones. Make them easier to distinguish by
displaying the hidden one with a different color (COLOR_YELLOW for color
themes and A_DIM for mono).

Changes from v1:
(https://patchwork.kernel.org/project/linux-kbuild/patch/20231228054630.3595093-1-tfiga@chromium.org/)
* Replaced A_DIM for color themes with COLOR_YELLOW, because the former
has no effect to black text on some commonly used terminals, e.g.
gnome-terminal, foot. Reported by Masahiro Yamada and Nicolas Schier.
I ended up with COLOR_YELLOW, as it seems to look comparatively dim
with mutliple light and dark color themes in Chromium hterm and
gnome-terminal.
