  [lldb/Reproducers] Skip API logging in the DUMMY macro

The purpose of the LLDB_RECORD_DUMMY macro is twofold: it is used in
functions that take arguments that we don't know how to serialize (e.g.
void*) and it's used by function where we want to avoid doing excessive
work because they can be called from a signal handler (e.g.
setTerminalWidth).

To support the latter case, I've disabled API logging form the Recorder
ctor used by the DUMMY macro. This ensures we don't allocate memory when
called from a signal handler.
