Aras Pranckevicius e7a21275c0 IO: print import & export times of Alembic & USD
Many existing importers/exporters do log the time it takes to system
console (some others log more information too). In particular, OBJ
(C++ & python), STL (C++ & python), PLY, glTF2 all log the time it
takes. However, neither USD nor Alembic do. And also it's harder to
know the time it takes there from a profiler, since all the work
normally is done on a background job and is split between several
threads (so you can't just find some top-level function and see how
much time it took).

This change:

- Adds import/export time logging to USD & Alembic importer/exporter,
- In the time utility class (also used by OBJ & STL), improve the
  output formatting: 1) print only one decimal digit, 2) for long
  times, print seconds and also produce a hours:minutes:seconds form.
