CLDR-18108 Give all languages a primary script: trivial cases

This change adds "primary" scripts to many languages in language_script.tsv.

This won't change likely subtags, rather this just future-proofs our data by recognizing a singular primary script, avoiding issues where ambiguities served customers the wrong script.

I also added scripts for languages in country_language_population.tsv that were missing.

 # Language Script Description
 
-The language\_script spreadsheet should list all of the language / script combinations that are in common modern use. The countries are not important, since their function has been overtaken by the country\_language\_population spreadsheet.
+The [`language\_script.tsv`](https://github.com/unicode-org/cldr/blob/main/tools/cldr-code/src/main/resources/org/unicode/cldr/util/data/language_script.tsv) data file should list all of the language / script combinations that are in common use. Usage by country is indicated in the [`country\_language\_population.tsv`](https://github.com/unicode-org/cldr/blob/main/tools/cldr-code/src/main/resources/org/unicode/cldr/util/data/country_language_population.tsv) spreadsheet.
 
-1. If the language and script are both modern, and the script is a major way to write the language in some country, then we should see that line marked as **primary**.
-2. Otherwise it should be marked **secondary**.
-
-Every language that is in official use in any country according to country\_language\_population  should have at least one primary script in the language\_script spreadsheet.
+1. Every language needs at least 1 script considered the **primary** script.
+    1. This data is used to determine [the most Likely language and region](likelysubtags-and-default-content) so there needs to be at least 1 primary value.
+    2. [Changed in v47] Include a primary script for historical languages (eg. Ancient Greek, Coptic). The primary script should reflect where the majority of the written corpus originates from.
+2. Languages written by significant populations with different scritps in different countries can have multiple **primary** scripts. The [likely subtags](https://www.unicode.org/cldr/charts/latest/supplemental/likely_subtags.html) patterns will use population counts to disambiguate the default script for each locale.
+3. Other scripts used for a language should be marked **secondary**.
 
 If a language has multiple primary scripts, then it should not appear without the script tag in the country\_language\_population.tsv. For example, we should not see "az", but rather "az\_Cyrl", "az\_Latn", and so on. For each country where the language is used, we should see figures on the script\-specific values. The values may overlap, that is, we may see az\_Cyrl at 60% and az\_Latn at 55%. However, the combination with the predominantly used script **must** have a larger figure than the others.
 
 This is also reflected in CLDR main: languages with multiple scripts will have that reflected in their structure (eg sr\-Cyrl\-RS), with aliases for the language\-region combinations.
