fix(mappings): 'langmap' with multibyte chars #40148

Problem:
On some non-US keyboards, like Estonian/Swedish/etc, widely used []
characters in vim are hard to type. One way to overcome this is to use langmap
option to map accented characters, that are in the same place as [] on US
keyboards to []. Unfortunately this does not work currently in neovim, it
cannot map multibyte characters via langmap.

Solution:
The fix iterates over characters in typeahead and key buffers, instead of bytes,
in getchar.c handle_mapping(). It does not handle macros though, these tests are
still failing when turned on.

Closes #2420
Closes #27776
