Add QPlatformTheme::MouseCursorTheme and MouseCursorSize
Also implement in QGenericUnixTheme/QKdeTheme/QGnomeTheme/QGtk3Theme.
On Wayland, there is wl_cursor_theme_load() and etc in wayland-cursor.h.
On X11/xcb, cursor theme and size are common, either in XCURSOR_THEME
and XCURSOR_SIZE envs, or in gsettings for gtk/gnome world.
On Windows, cursor theme is part of theme file, see SetWindowTheme in
https://learn.microsoft.com/en-gb/windows/win32/api/uxtheme/nf-uxtheme-setwindowtheme .
For system settings, for example on Windows 10, Mouse Settings,
Additional mouse options, Pointers Tab, Scheme.
On macOS, it looks like cursor theme is deprecated.
