tracing: Add DECLARE_TRACE_WITH_CALLBACK() macro
Introduce a new 'DECLARE_TRACE_WITH_CALLBACK()' macro, so that tracepoints can associate an external register/unregister function. This prepares for the syscalls tracer conversion to trace events. We will need to perform arch level operations once a syscall event is turned on/off, such as TIF flags setting, hence the need of such specific callbacks.
