utf8: add support for unicode combining characters
This feature lets foot combine e.g. "a\u0301" to "á".

We first check if the current character (that we're about to print) is
a combining character, by checking if it's in one of the following
ranges:

* Combining Diacritical Marks (0300–036F), since version 1.0, with
  modifications in subsequent versions down to 4.1
* Combining Diacritical Marks Extended (1AB0–1AFF), version 7.0
* Combining Diacritical Marks Supplement (1DC0–1DFF), versions 4.1 to 5.2
* Combining Diacritical Marks for Symbols (20D0–20FF), since version
  1.0, with modifications in subsequent versions down to 5.1
* Combining Half Marks (FE20–FE2F), versions 1.0, with modifications
  in subsequent versions down to 8.0

If it is, we check if the last cell appears to contain a valid symbol,
and if so, we attempt to compose (combine) the last cell with the
current character, using utf8proc.

If the result is a combined character, we replace the content in the
previous cell with the new, combined character.

Thus, if you select and copy the printed character, you would get
e.g. "\u00e1" instead of "a\u0301".

This feature can be disabled. By default, it is enabled if the
utf8proc library is found, but can be explicitly disabled, or enabled,
with 'meson -Dunicode-combining=disabled|enabled'.
