Fix python fbx tests (#2171)

* Update fbx test dbgsg files

Remove rc products from fbx test expected output
Update warning counts for 2 of the tests - these are due to missing material properties
Add SkipAtomOutput setting to disable atom material and mesh processing in scene as these pull in a lot of external dependencies to Process
Removed BlendShapeData and MeshData debug output of positions/normals/faces
Updated ManifestImportRequestHandler to remove warning about Joining 2 absolute paths
Updated AssImpMaterialImporter to use new GenerateRelativeSourcePath API to fix issue where relative path generation failed with tmp project directories

* Add comment for setting

* Add override dbgsg file to python test

The mesh optimizer specifically avoids creating optimized nodes for nodes that are not selected, resulting in a different scene graph that requires a different dbgsg file to compare with

* Replace hardcoded passing of specific registry setting to instead pass all registry settings to AssetBuilder
