CLDR-16346 Fix initials 2

[macchiati]

CLDR-16346

Detect and fix inconsistencies between initial pattern and literals between initial fields. Handles the "J. R.R. Tolkien" case.

From Person Names WG agenda

Overall Recommendations AGREED

1. For en, en_GB: Switch to J.R.R. Tolkien.
   a. In en, drop space between initial fields, drop space in initial sequence pattern,
   b. In en_GB, en_001, change to ^^^.
2. For ar, move period to ‘initial’. Was:
   a. {0} R Gillam→R. Gillam
   b. {0}. {1}. R. B. Gillam (same)
3. For nl, drop the space in the adjacent fields.
   a. Will look like en, en_GB in (i) above
4. For yue, the sorting forms need spaces, eg
   a. {surname-core}{given-initial}{given2-initial}
   b. The FSR will cause them to be removed or replaced by ·
   c. {surname-core} {given-initial} {given2-initial}

Ah, that's the magic formula to kick the tests off!
