CLDR-19054

• This PR completes the ticket.

Added display names for key hc new types c12, c24, deriving them from the existing types h11,h12,h23,h24 by deleting the parenthesized ranges.

• Added "core" versions if the locale had them for h11,h12,h23,h24 and used same draft status as the existing h11,h12,h23,h24.
• Did not do this for locale to since the c12, c24 were not derivable in the same way. In that locale the existing h11,h12,h23,h24 are unconfirmed anyway.
• Made some spot fixes to the existing h11,h12,h23,h24 in certain locales:
  • ak: h12, fixed missing final paren
  • as: h23/core was completely bogus, fixed to be like other cores
  • ccp: h23, fixed missing space
  • kxv: h12, fixed spaces around range
• For several locales as, ne, ti the "core" value is repeated; did not change but will file a ticket.

Also made other necessary updates:

• Removed "deprecated" status for c12, c24 in common/bcp47/calendar.xml
• In unit test TestCoverageLevel.TestCoverageCompleteness allowed display names for c12, c24 to be at comprehensive, at least for now.
