lima: split draw calls on 64k vertices

lima: split draw calls on 64k vertices

The Mali400 only supports draws with up to 64k vertices per command.
To handle this, break the draw_vbo call into multiple commands.
Indexed drawing is left to a separate code path.
This implementation was ported from vc4_draw_vbo.
