meson: add -Dterminfo-base-name option

This defines the base name of the generated terminfo files. It
defaults to the value of -Ddefault-terminfo (i.e. 'foot')

Example:

  meson -Ddefault-terminfo=foot-bananas -Dterminfo-base-name=foot-apples

The generated terminfo files will be

* terminfo/f/foot-apples
* terminfo/f/foot-apples-direct

The default value of $TERM will be 'foot-bananas'

 ### Added
 
 * `[tweak].bold-text-in-bright-amount` option ([#1434][1434]).
+* `-Dterminfo-base-name` meson option, allowing you to name the
+  terminfo files to something other than `-Ddefault-terminfo`. Use
+  case: have foot default to using the terminfo from ncurses (`foot`,
+  `foot-direct`), while still packaging foot's terminfo files, but
+  under a different name (e.g. `foot-extra`, `foot-extra-direct`).
