Use the correct function parameter name in ucs_get_fallback() to prevent
kernel-doc warnings:
Warning: drivers/tty/vt/ucs.c:218 function parameter 'cp' not described in 'ucs_get_fallback'
Warning: drivers/tty/vt/ucs.c:218 Excess function parameter 'base' description in 'ucs_get_fallback'
Fixes: fe26933cf1e1 ("vt: add ucs_get_fallback()")

This is the code querying the newly introduced tables.

The in_range() helper accepts a start and a length, not a start and
an end.

Width tables are now split into BMP (16-bit) and non-BMP (above 16-bit).
This reduces the corresponding text size by 20-25%.
Note: scripts/checkpatch.pl complains about "... exceeds 100 columns".
Please ignore.

Try replacing any decomposed Unicode sequence by the corresponding
recomposed code point. Code point to glyph correspondance works best
after recomposition, and this apply mostly to single-width code points
therefore we can't preserve them in their decomposed form anyway.

This removes the table from ucs.c and substitutes the generated tables
from ucs_width_table.h providing comprehensive ranges for double-width
and zero-width Unicode code points.
Also implements ucs_is_zero_width() to query the new zero-width table.

This will make it easier to maintain. Also make it depend on
CONFIG_CONSOLE_TRANSLATIONS.
