bug#66470: 29.1; Provide Urdu input method

[Rahguzar]

Dear Emacs developers,

Emacs should provide an Urdu input method. The closet input methods
available are those for Farsi. However Urdu has additional letters which
can't be inputted using those and divergence between Urdu and Farsi
makes some of the choices less than ideal for Urdu.

I have written a simple input method for Urdu which I will attach as a
patch with a followup email for review and eventual inclusion. I have
questions about quail which I asked at
https://lists.gnu.org/archive/html/help-gnu-emacs/2023-10/msg00082.html
. If someone on this list knows the answer to those please let me know.

Thanks in advance,
Rahguzar
