Use the "shipped" mechanism to copy pre-generated tables to the build
tree by default. If GENERATE_UCS_TABLES=1 then they are generated at
build time instead. If GENERATE_UCS_TABLES=2 then
gen_ucs_recompose_table.py is invoked with --full.

vt: update gen_ucs_width_table.py to make tables more space efficient2025-04-26T09:22:04+00:00Nicolas Pitrenpitre@baylibre.com2025-04-17T18:45:14+00:00urn:sha1:ad934777f0f15c8cea042b6a81deaa7fe53b6dea
Split table ranges into BMP (16-bit) and non-BMP (above 16-bit).
This reduces the corresponding text size by 20-25%.

The table in ucs.c is terribly out of date and incomplete. We also need a
second table to store zero-width code points. Properly maintaining those
tables manually is impossible. So here's a script to generate them.
