The previous version returned the incorrect size from the position map when
blendshapes are present in the model. When there are blendshapes, the
vertex welding is disabled, and nothing is inserted into the position map.
However, the position map's size was being used to dictate how many
elements to create in the skinning info. The skinning info tries to
compensate for an incorrect max vertex index by resizing its underlying
vector when adding an influence, but that was using the index as the new
size of the vector, so it was off by one. This fixes both errors.

* 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.

The thought behind Array2D was that it would be more efficient from a
memory allocation perspective to have one fixed buffer that grows than
it would be to have a vector of vectors. In reality, the runtime of
inserting into the middle of one large buffer, and shifting all the
resulting elements, ends up far outweighing any memory allocation
overhead.
In the mesh optimizer, things are added to the end of each sub-vector
one by one. It isn't known up front how many elements each sub-vector
will have. With vertex welding enabled, it is far more likely that a
given vertex will be influenced by a large number of joints. When using
the Array2D to store the influences, and a vertex with a low index has
more than 4 influences, those influences have to be inserted into close
to the front of the big vector, and all the other elements shifted.
Array2D was doing this with a linear shift, shifting the elements by 1
at a time, and not providing any exponential growth on the amount of
elements reserved by each sub-vector. The result is a linear insertion
time.
By contrast, using vector<vector<Influence>> instead gives us back the
amortized constant insertion time. Since the skin influences are just
added to the end of each sub-vector, no shifting of the elements is
necessary. And since the amount of original vertex indices is known up
front, the number of sub-vectors can still be pre-created, so the
sub-vectors themselves never need to shift.

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.

* Helios - LYN-3250 - Fixed morph targets for meshes that had multiple materials (#374)
Fixed morph targets for meshes that had multiple materials and were split by AssImp: Recombined them into one mesh in the O3DE scene graph, so the behavior would match FBX SDK.
This is cherry-picked from #311
When processing meshes with blend shapes, the mesh optimizer disables the
optimize duplicates setting, to prevent potential vertex reodering that
could cause the base mesh vertices to become out of sync with the blend
shape. However, it will still reorder vertices based on their material.
It places all triangles that use the same material in the same submesh,
grouping them together in the resulting mesh. The SceneAPI does not track
material ids for blend shapes. To ensure that the blend shape triangles are
reordered in the same way as the base shape, this change makes the blend
shape optimization use the material id from the base shape.
- Remove some references to gEnv->pRenderer/GetIEditor()->GetRenderer() that is now always null.
- Restore the debug console to existence.
- Stop building the following in preparation for their removal:
Code/CryEngine/Cry3DEngine/*
Code/CryEngine/RenderDll/*
Code/Tools/CryFXC/*
Code/Tools/HLSLCrossCompiler/*
Code/Tools/HLSLCrossCompilerMETAL/*
Code/Tools/RC/*

- Reexport cloth assets with AssImp ON. These was necessary because AssImp collects a different name for the color streams than FbxSDK and therefore they needed to be reassigned in the cloth rule.
- Adding '_optimized' string to a global variable and using StringFunc RChop to remove it for a string.
