Subject: Feature/test improvements (#934)

* First pass extract the test information by 'running tests'.

* * Checking renderer availablilty
* Using TestInfo to determine which tests are run and synthesized
* Display if test is synthesized and what render api it's targetting

* * Improved comments
* Removed some dead code

* Display ignored tests.

* TestInfo -> TestRequirements

* * Added DIAGNOSTIC_TEST type - test always runs (ie has no requirements).
* Made diagnostic tests use DIAGNOSTIC_TEST
* TestInfo -> TestRequirements
* TestDetails holds TestRequirements and TestOptions

* Fix debug typo.
