Fix disabled and inactive group palettes for windows native style

The dark mode related changes for windows didn't update disabled and
inactive group palettes, and this makes text in certain context
(such as menu bar) appear with enabled color. The windows theme API
populateLightSystemPalette() is responsible for this and it updates
palettes for color roles and certain inactive scenarios but not for
disabled.

This patch set makes existing systemPalette(Qt::ColorScheme) to be
available in QWindowsTheme and it updates palette depending on color
scheme. From now on, this API updates palettes for windows native
style. Its to be noted that window native style use light palette
irrespective of color scheme.

Fixes: QTBUG-114821
