Update to Unicode 13.0.0.

* lib/gen-uni-tables.c (is_WBP_MIDLETTER): Add character 0x055F.
(get_wbp): Assign value WBP_ALETTER to the characters 0x02E5..0x02EB,
0x055A, 0x058A, 0xA708..0xA716.

* lib/gen-uni-tables.c (LBP_CP1, LBP_CP2, LBP_OP1, LBP_OP2): New enum
values.
(LBP_OP, LBP_CP): Assign artificial values.
(get_lbp): Use the unicode_width[] table to assign LBP_CP1, LBP_CP2
instead of LBP_CP, and LBP_OP1, LBP_OP2 instead of LBP_OP. Update such
that unilbrk/lbrkprop.txt comes out as expected.
(debug_output_lbp): Print either LBP_CP1 or LBP_CP2 as LBP_CP. Print
either LBP_OP1 or LBP_OP2 as LBP_OP.
(lbp_value_to_string): Handle LBP_CP1, LBP_CP2, LBP_OP1, LBP_OP2 instead
of LBP_CP, LBP_OP.
(output_lbrk_rules_as_tables): Treat LBP_CP and LBP_OP as macros that
map to two table rows/columns. In rule LB30, use only LBP_OP1 instead of
LBP_OP, and only LBP_CP1 instead of LBP_CP. Simplify rule LB22.
* lib/unilbrk/lbrktables.h (LBP_CP1, LBP_CP2, LBP_OP1, LBP_OP2): New
enum values.
(LBP_OP, LBP_CP): Remove enum values.
(unilbrk_table): Update declaration.
* lib/unilbrk/u8-possible-linebreaks.c (u8_possible_linebreaks_loop):
Add a test for East Asian opening parenthesis.
* lib/unilbrk/u16-possible-linebreaks.c (u16_possible_linebreaks_loop):
Likewise.
* lib/unilbrk/u32-possible-linebreaks.c (u32_possible_linebreaks_loop):
Likewise.

* lib/uniwidth/width.c (nonspacing_table_data, nonspacing_table_ind):
Update.
(uc_width): Assign width 2 to the characters 0x16FF0..0x16FF1,
0x18AF3..0x18CD5, 0x18D00..0x18D08, 0x1F6D6..0x1F6D7, 0x1F6FB..0x1F6FC,

0x1FAC0..0x1FAC2, 0x1FAD0..0x1FAD6.
Assign width 1 to the characters 0x1F93B, 0x1F946.
* tests/uniwidth/test-uc_width2.sh: Expect width 0 for the characters
0x0B55, 0x0D81, 0x1ABF..0x1AC0, 0xA82C, 0x10EAB..0x10EAC, 0x111CF,
