render/gles: Simplify textures a bit

Browse source 
We don't need our own enum for types. Instead we just use
GL_TEXTURE_{2D,EXTERNAL_OES}, which already describes usage.

Also fixes a situation where we were using GL_TEXTURE_2D in a situation
we should not have. wl_drm buffers are always GL_TEXTURE_EXTERNAL_OES,
no matter if they're RGB or any other format.
