RT #122341 treat all of 0x0a-0x0d,\x85,\x2028,\x2029 as newlines

The script tools/dev/gen_charset_tables.pl was not used because it removes
character properties of chars in the range of 0x81 to 0xFF. Additionally,
u_iscclass now checks for characters with enum_cclass_newline property,
which it did not do at all before.
