Hyunjun Ko a80e10ac5c libs: display{egl,glx}: cache GstVaapiTextures
instances when created and reuse

This patch improves performance when glimagesink uploads a GL texture.

It caches the GStVaapiTexture instances in GstVaapiDisplay{GLX,EGL}, using an
instance of GstVaapiTextureMap, so our internal texture structure can be found
by matching the GL texture id for each frame upload process, avoiding the
internal texture structure creation and its following destruction.
