Also, for mac, make --time-trace-file and --time-trace-granularity
*not* imply --time-trace, to match behavior of the ELF port.

My goal here is to have a short, single flag I can use to get LLD to write a trace, and to make ELF and MachO (and, in time, COFF – this requires teaching TimeProfiler to write a short summary to stdout and to switch lld/COFF to TimeTraceScope) behave the same way.
