Remove unused upstream DTrace provider implementations that are duplicates

Browse Source 
of providers under sys/cddl/dev/. Also remove sdt_subr.c, which isn't used
in FreeBSD's SDT implementation.

* Regardless of platform, the stack frames look like this in the case of the

*
* profile_fire
* cyclic_expire
* cyclic_fire
* [ cbe ]
* [ interrupt code ]
*
* On x86, there are five frames from the generic interrupt code; further, the
* interrupted instruction appears as its own stack frame, giving us a total of
* 10.
*
* On SPARC, the picture is further complicated because the compiler
* optimizes away tail-calls -- so the following frames are optimized away:
*
* profile_fire
* cyclic_expire
*
* This gives three frames. However, on DEBUG kernels, the cyclic_expire
* frame cannot be tail-call eliminated, yielding four frames in this case.
*
* All of the above constraints lead to the mess below. Yes, the profile
* provider should ideally figure this out on-the-fly by hitting one of its own
* probes and then walking its own stack trace. This is complicated, however,
* and the static definition doesn't seem to be overly brittle. Still, we
* allow for a manual override in case we get it completely wrong.
