This commit is a followup of {D7649}, and ports the USD tests to the new
testing approach. It moves test code from `tests/gtests/usd` into
`source/blender/io/common` and `source/blender/io/usd`, and adjusts the
use of namespaces to be consistent with the other tests.
I decided to put one test into `io/usd/tests`, instead of
`io/usd/intern`. The reason is that this test does not correspond with a
single file in that directory; instead, it tests Blender's integration
with the USD library itself.
There are two new CLI arguments for the Big Test Runner:
- `--test-assets-dir`, which points to the `lib/tests` directory in the
SVN repository. This allows unit tests to find test assets.
- `--test-release-dir`, which points to `bin/{BLENDER_VERSION}` in the
build directory. At the moment this is only used by the USD test.
The CLI arguments are automatically passed to the Big Test Runner when
using `ctest`. When manually running the tests, the arguments are only
required when there is a test run that needs them.
For more info about splitting some code into 'common', see
rB084c5d6c7e2cf8.
No functional changes to the tests themselves, only to the way they are
built & run.
