Move the QPalette::resolveMask into the private

With 64bits, the mask is exhausted with the 21 colors x 3 color groups
we have right now.

In order to support accent colors, we need more palette entries. By
moving the mask into the d-pointer, we can extend QPalette within
the Qt 6 series, without breaking binary compatibility.

The resolveMask/setResolveMask methods that take integers are
documented as internals, so we can change those signatures after
Qt 6.0 as well.

As a side effect, setting the resolve mask on a QPalette detaches now.
Setting a mask is in most cases done on the result of
QPalette::resolve, which is usually detached already. And the QPalette
default constructor will have to detach from the global application
palette if that palette has any colors set explicitly.
