Jan Drewniak 1d379b3baa [refactor] Re-organize CSSCustomProperties.less
Organizes the code in CSSCustomProperties.less into
3 separate groups:
- Forced night-mode,
- auto night-mode
- night-mode helpers.

Also applies `color: var(--color-base)` to both .skin-invert
and .notheme to address situations where color is
defined by inheritance.
