renderer: add more uniforms to the screen shader (#11986)

These are: pointer_shape from the cursor-shape-v1 protocol prepared for v2, along with left_ptr...bottom_right_corner and killing (Hyprland specific)
           pointer_shape_previous with
           pointer_switch_time to blend between shapes
           pointer_size scaled size as used by the normal cursor
           pointer_pressed_positions[32] with
           pointer_pressed_times[32] and
           pointer_pressed_killed(32 bits) for click/touch animations and if they killed something
           pointer_inactive_timeout with
           pointer_last_active to smoothly fade the pointer out
           pointer_hidden to hide it when the cursor is hidden (excluding by cursor:invisible as this config value can be used to turn off the normal cursor, which is useful when drawing it with the screen shader)
