Progressive Lightmapper


Steps to repro:
1. Open the attached project;
2. In the Test Runner window (Window>General>Test Runner) under the Baking foldout section select BakeLightingGPU test;
3. In the Test Runner window under the Baking foldout section Shift-click and select BakeLightingGPUSubtractive to select all GPU PLM baking tests in this section;
4. In the Test Runner window right-click on the selection and press Run Selected button;
5. Wait until the tests are executed.

Expected result:
Selected tests pass successfully.

Actual result:
The tests fail with the following errors:
`Assertion failed on expression: '!useRadeon || (!radeonDenoiser.IsNull() && radeonDenoiser->GetRefCount() <= 1)'
`OpenCL Error. Falling back to CPU lightmapper. Error callback from context: IntersectionApi::Commit failure: likely out of GPU resources.`
