Fix many printf warnings (mono/mono#16484)

Fix many printf warnings (mono/mono#16484)

* Do not `printf` `long long` or `unsigned long long`.

*Do* printf `gint64` or `guint64`.

Do not printf %ll.
Do not printf %z.

 gint64 ==  int64_t, which could be long, or long long, or maybe other
guint64 == uint64_t, ditto

For printing gint64/guint64, use PRId64, PRIx64, etc.
For printing gsize/gssize, use `G_GSIZE_FORMAT` (seems like excess `G`).

%z definitely would warn for every single use, with Mingw.

And %ll might also, since on 64bit platforms, gint64 tends to be
long, not long long, and would merit %l not %ll.
(No matter that %ll is merited on 32bit, and the behavior
would then be correct on both.).

If there becomes a system w/o PRId64 etc., and it is a 64bit system,
then we could use %l under a portable name.
Or %I64. This appears unlikely (unless reach is extended to older Windows runtime).

Note that PRIxPTR for gsize/intptr_t may be a good idea too.
