* Default setting when no tangents rule: MikkT tangents.
* Calculates tangents/bitangents for all available uv sets.
* Creates tangent/bitangent data in in case they are not existing yet (as in: the source scene contains tangents/bitangents)
* Overwrites the tangent/bitangent data from the source scene in case MikkT is wished.
* Added helper functions to create tangent/bitangent scene nodes, finding tangent/bitangent data for a given uv layer and calculating the number of uv layers provided by the mesh scene node.

This fixes a bug where a Python script file would be run on a scene file
that didn't have a script file set.
Added a general case version to SceneBuilderWorker.cpp, to make it easy
to mark all scene files as dirty.
Automated tests for this will come in a separate pull request.

* 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 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

* Determine the original vertex index based on the position
The Assimp library does not expose the FBX control point indices. This
change causes vertices that are close enough in their position to be
considered as coming from the same control point. This allows the mesh
optimizer to consider vertices with the same control point index (or
"original vertex index" as it is called in the code) for deduplication.

Some nodes have aiBones created by AssImp even though they aren't bones. Filter these out by looking through the node graph and only considering

Use first offsetMatrix for a bone (there may be multiple) and calculate using offsetOfParent * inverseRootOffset * rootOffset * inverseOffset
(cherry picked from commit a8eae976dda39ad28f9aa235e1e6ba34715ac48a)
# Conflicts:
# Code/Tools/SceneAPI/FbxSceneBuilder/Importers/AssImpTransformImporter.cpp
For bone nodes, the Transform is computed by multiplying the parent offsetMatrix by the inverse of the node's offsetMatrix
Note that this currently disables the LimitBoneWeights option since that results in the removal of bone nodes that are not attached to a mesh.
Without the bones there is no way to retrieve the offsetMatrix, so the Transform cannot be computed correctly
Fixes LYN-3755
* Abort calls in AssImp, which occur when an assert is hit in builds that have asserts enabled (like debug) no longer generate a popup. Instead, they are captured as errors and an asset processing failure.
* Added missing include
* Added check for _WRITE_ABORT_MSG, so platforms that don't have it but have signals enabled (Linux profile) compile correctly
