Alpha1 integration for CLDR 47.

Includes updates for tzdata to 2024b and adding new measurement units (duration-night and light-speed).

Changes in unit tests

• Updated expected result for changes in likelySubtags
• Updated time zone names for Australia
• Updated locale tests using deprecated big5 collation
• Manually updated changes for timedata for en_GS and en_PL, newly added en locales which doesn't contain this data. This will be landed in CLDR-18268 Add timeData for GS cldr#4319, and will not need to be manually updated in next alpha integration

Known issues:

• There is still a problem with per billion unit (a.k.a 1e9). Removed the entry from test data for that unit

The data file changes are practially unreviewable. I am ok rubber-stamping them, but it would be better to first do a null integration of the same data as in the last integration, but with the tool change and with CLDR version number 47. Easy to rubber-stamp. Then integrating actual 47 alpha would be limited to the real changes.

And if real data changes exceed 1000 files (or maybe an even lower threshold), please split them into multiple commits.

Why are we getting an empty Finnish brkitr file? Is there a new empty Finnish CLDR file?

Same question for sv=Swedish.

[pedberg-icu]

Hmm. We no longer have fi or sv entries in icu4c/source/data/xml/brkitr/*.xml which was my first guess at why these might be there.

[markusicu]

Progress figuring this out?

[DraganBesevic]

My best guess is that fi or sv entries in icu4c/source/data/xml/brkitr/*.xml got removed, but they are still somewhere in some list for building .txt files from that repo. I will look at it

[pedberg-icu]

If I have a chance today I will also try do an integration to investigate this...

But I see that in CLDR, common/segmentation/ still has word break tailorings for fi and sv. Perhaps these need to be removed; even thought the contents of the tailorings are not converted for ICU, the presence of the files may affect ICU. This probably needs to be discussed with Mark.

[pedberg-icu]

The fi/sv wordbreak tailorings were removed in ICU in October 2024 per ICU-22941 for ICU 77, so this is the first integration of CLDR for ICU 77. Those word break tailorings were added in CLDR in Aug 2022 per CLDR-15910 for CLDR 42. Need to file a CLDR ticket to remove them.

[pedberg-icu]

Will ignore for this integration, address in CLDR for next integration
