Normative: Add 8 new numbering systems for Unicode 16

Unicode 16 added 8 new numbering systems for the newly
added 5,185 new characters, including 3,995 additional Egyptian Hieroglyph characters plus seven new scripts, seven new emoji characters, and over 700 symbols from legacy computing environments.
see https://blog.unicode.org/2024/09/announcing-unicode-standard-version-160.html

CLDR add that in unicode-org/cldr#3658
which will be available in ICU 76

This PR update the ECMA402 spec to include that new numbering systems. 

We should consider merging it after ICU 76.1 is wildely available to implementer. We probably should discuss this in TG2 around Nov. or Dec. 2024.
