screen-cast-window: Use buffer bounds in place of frame bounds

Browse Source 
The frame bounds as returned by `meta_window_actor_get_frame_bounds()`
would be used as cropping values when streaming a window content.

But, as its name implies, it returns the actual frame bounds, whereas we
may want to include the whole buffer, to include client side shadows for
example.

Rename the `get_frame_bounds()` API to `get_buffer_bounds()` (which was
previously partly removed with commit 11bd84789) and return the actual
buffer bounds to use as the cropping area when streaming a window.
