cursor: Better xcursor implementation (#7178)

* xcursor: bootleg xcursors into its own manager

implent XCursorManager and load themes based on librarypath and its
dir, now we catch all supplied theme files. and also implent animated
cursors. also refactor a bit of spaghetti regarding xcursors in
CursorManager.

* hyprcursor: fix buffer leak

animated cursors are creating a new buffer for each image, ensure we
drop the buffers so it continously doesnt build up in infinity.

* cursormgr: use eventloopmgr for animation

use EvenloopManager for timers instead of adding it directly to
m_sWLEventLoop and using its related wl_* functions.
