sim: add ATTRIBUTE_PRINTF / ATTRIBUTE_NULL_PRINTF where necessary

I finally got the all-targets sim building with Clang, these are all the
instances where an ATTRIBUTE_PRINTF or ATTRIBUTE_NULL_PRINTF attribute
needed to be added to avoid errors like:

    /home/simark/src/binutils-gdb/sim/aarch64/../common/sim-profile.c:464:19: error: format string is not a string literal [-Werror,-Wformat-nonliteral]
        vfprintf (fp, fmt, ap);
                      ^~~
There are more fixes needed to get everything building, but adding these
attributes is trivial enough, so I send them all in a single patch.

Adding the format attributes introduces some format string errors when
building with GCC (because now format strings are checked), so
corresponding changes are needed to avoid breaking the build.  Other
than simple format string specified changes, there is this one:

    /home/simark/src/binutils-gdb/sim/aarch64/../common/hw-events.c: In function 'hw_event_queue_schedule':
    /home/simark/src/binutils-gdb/sim/aarch64/../common/hw-events.c:95:15: error: too many arguments for format [-Werror=format-extra-args]
       95 |         NULL, dummy);
          |               ^~~~~

We can fix it and avoid using a dummy variable by simply calling
hw_event_queue_schedule_tracef instead of
hw_event_queue_schedule_vtracef.
