render/gles2: assert that GL_OES_EGL_image_external is supported

The target is set to GL_TEXTURE_EXTERNAL_OES when
EGL_EXT_image_dma_buf_import_modifiers [1] returns an external_only
flag. That spec states:

> In order to support imports for the GL_TEXTURE_EXTERNAL_OES target, a
> compatible OpenGL ES implementation supporting GL_OES_EGL_image_external
> must be present.

Fail hearder when a driver doesn't follow the spec instead of
skipping rendering.

See [2].
