This PR uses renderdoc for frame capturing when enabled. It enabled an easier workflow for frame capturing. - Capture GPU API calls from test cases - Capture GPU API calls from background threads - Capture GPU API calls from background rendering. Renderdoc is an important GPU debugger used by the Eevee/ Viewport module. Previously we needed to change code in order to record background rendering, that could on its own lead to other side-effects. The integration with renderdoc can be enabled using `WITH_RENDERDOC=On` compiler option. `GPU_debug_capture_begin` and `GPU_debug_capture_end` can be added to the section of the code you want to debug. When running Blender inside renderdoc this part will automatically be captured. All GPU test cases are now guarded by these calls. In order to capture the test cases you need to start the test cases from renderdoc and the captured GPU API calls will appear where each capture is a single test case.
