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].
