The EGL context can only import and blit an EGLImage if the backing DMA buffer has a format modifier combination that is advertised as supported and not marked as "external_only". When the context can't blit the imported image, we can still paint using it GL_OES_EGL_image_external using the texture target GL_TEXTURE_EXTERNAL_OES. However, treat drivers who doesn't support modifiers at all as if they do support blitting, if the modifier is 'linear', to avoid regressions.
