add %Wi %Wu %Wd for pretty-printing wides_int

This fails bootstrap at:

libcommon.a(pretty-print.o): In function `pp_format(pretty_printer*,
text_info*)':
/home/manuel/test1/src/gcc/pretty-print.c:543: undefined reference to

pretty-print.c is used all over the place and adding a dependency on
wide-int.cc will bring gmp and other stuff that is currently  not used (nor
linked with) various helper programs. If wide-int is only printed in the
middle-end, perhaps it is sufficient to add it to default_tree_printer.
Otherwise, it needs to be added to every FE. This is not difficult just
tedious. The difficult part is the c-format.c changes (I wish someone would fix
https://gcc.gnu.org/PR47781 so we can use a simpler syntax to define our custom
specifiers; in addition to the positive synergies it will bring with other GNU
projects that use custom specifiers and wish to use -Wformat).
