This removes mostly benign (but noisy) messages about "Failed to find builder dependency".
Changed AssetUtils::GetPossibleDepenencyPaths to return all possible source paths, rather than stopping when one is found. This function is now used to report a list of all possible source dependencies, so that CreateJobs will get called by the AP whenever a file shows up at one of those locations. If a file was missing before and then appears, this will cause the builders to wake up and add the appropriate job dependencies on the new files. In ShaderVariantAssetBuilder and MaterialBuilder, we now use GetPossibleDepenencyPaths to report source dependencies rather than job dependencies. We only report a job dependency when the actual source file has been identified. This should all now be consistent with the intended design of the AP's dependency systems (the prior approach was a hack based on misunderstanding of what source dependencies are).
SrgLayoutBuilder's change is a bit tricky. The above changes did not fix all of the "Failed to find builder dependency" messages because AzslBuilder sometimes skips particular files in CreateJobs. When this happens, it is invalid to report an AzslBuilder job dependency on that file. So I copied the same conditional code that is used to skip an azsli file in CreateJobs, and used that to skip AddAzslBuilderJobDependency() in SrgLayoutBuilder as well.
With all these changes combined, I do think we've solved the issue where jobs fail to evict outdated jobs, as described in ATOM-15134. However, we are not yet seeing the iteration time improvements we were hoping for. Before these changes I was seeing roughly a 0.5 minute delay for the initial change, and a 2 minute delay for a subsequent change. With these changes it's more like 0.5 mibutes and 1.5 minutes. It appears that the AP scan is being starved by all the AssetBuilder processing going on, and perhaps IO contention. I suspect that this will be greatly improved on the development branch where we no longer have AzslBuilder and SrgLayoutBuilder slowing things down.
