[PATCH] emacs: override enriched-decode-display-prop for text/enriched display

[Jani Nikula]

Switch to a local version of enriched-decode-display-prop if we
encounter a text/enriched part. This is to mitigate
https://bugs.gnu.org/28350. Normally it would be prudent to remove the
override afterwards, but in this case just leave it in.
