tracing: dedup TRACE macros & rename to TRACEPOINT

Browse Source 
This deduplicates the TRACEx macros by using systemtaps STAP_PROBEV[0]
variadic macro instead of the DTrace compability DTRACE_PROBE[1] macros.
Bitcoin Core never had DTrace tracepoints, so we don't need to use the
drop-in replacement for it. As noted in pr25541[2], these macros aren't
compatibile with DTrace on macOS anyway.

This also renames the TRACEx macro to TRACEPOINT to clarify what the
macro does: inserting a tracepoint vs tracing (logging) something.
