tracing: Remove show_format and related macros from TRACE_EVENT
The previous patches added the use of print_fmt string and changes
the trace_define_field() function to also create the fields and
format output for the event format files.

The above shows the size of the vmlinux after this patch set
compared to the vmlinux-orig which is before the patch set.
This saves us 27k on text, 1k on bss and adds just 4k of data.
The total savings of 24k in size.
