Series [v2,1/4] ui/gtk-egl: un-tab and re-tab should destroy egl surface and context | expand

Commit Message

If guest fb is backed by dmabuf (blob-resource), the texture bound to the
old context needs to be recreated in case the egl is re-initialized (e.g.
new window for vc is created in case of detaching/reattaching of the tab)

v2: call egl_dmabuf_release_texutre instead of putting 0 to dmabuf->texture
