Make it so wlr_gles2_texture is ref'counted (via wlr_buffer). This is similar to wlr_gles2_buffer or wlr_drm_fb work. When creating a wlr_texture from a wlr_buffer, first check if we already have a texture for the buffer. If so, increase the wlr_buffer ref'count and make sure any changes made by an external process are made visible (by invalidating the texture). When destroying a wlr_texture created from a wlr_buffer, decrease the ref'count, but keep the wlr_texture around in case the caller uses it again. When the wlr_buffer is destroyed, cleanup the wlr_texture.
