Migrate render-test away from deprecated compile request API (#6514)

* Add a simple interface parameter test

Since there's no documentation, it's nice to have a simple test case in order to
experiment with this feature of the testing framework.

* Add shader entry point attributes to tests

* Fix specialization arguments for tests

- Add some missing arguments
- Rremove one extraneous argument.

* Stop using deprecated compile request in render-test

Use a session object instead of the deprecated compile request object.
This closes issue #4760.
