wmaker: add support for _NET_WM_MOVERESIZE

Browse Source 
This patch adds support for _NET_WM_MOVERESIZE hint as defined in EWMH
which allows a window without decorations to manage itself (moving/resizing).
The purpose is to fix the issue mentioned at https://github.com/window-maker/wmaker/issues/20

Tested with VS Code, Google Chrome, Steam and Discord.

Specs are available at https://specifications.freedesktop.org/wm/1.5/ar01s04.html#id-1.5.4
