Fix disabled button color in Linux (X11/Wayland)

Browse Source 
The palette mapping table (as read from gtk widget) maintained in
QGtk3Storage misses information of QPalette::Button and
QPalette::ButtonText role for QPalette::Disabled color group. This
cause disabled button widget to be rendered with incorrect palette
(such as in dark color scheme, light palette had been used).

This patch fixes this issue by extending palette mapping in
QGtk3Storage for disabled color group of button role.

Fixes: QTBUG-113486
Pick-to: 6.6.0 6.5
