Remove the Windows XP style from public accessibility

Later, the Windows XP style will be removed entirely by means of
being merged with the Windows Vista style (which inherits from the
XP style).

There was actually no reason for these styles being separate
classes in the first place, because both result in the same
appearance for controls on the running version of Windows.
Therefore, the windowsxp style merely appears as a "broken"
version of the windowsvista style, with only minor differences
based on the additional metrics that the vista style provides.
The windowsxp style does NOT, and never did, allow users to get
a Windows XP style appearance on Windows 7 and above (which is
currently Qt's minimum supported platform). Therefore, now that
Qt no longer supports Windows XP, the windowsxp style is unusable.

[ChangeLog][QtWidgets] The windowsxp style is no longer available
as a separate style, because it did not (and cannot) actually
provide an XP-style appearance on currently supported Qt platforms.
