Override layers are a standard feature of Alembic, where archives can override data from other archives, provided that the hierarchies match. This is useful for modifying a UV map, updating an animation, or even creating some sort of LOD system where low resolution meshes are swapped by high resolution versions. It is possible to add UV maps and vertex colors using this system, however, they will only appear in the spreadsheet editor when viewing evaluated data, as the UV map and Vertex color UI only show data present on the original mesh. Implementation wise, this adds a `CacheFileLayer` data structure to the `CacheFile` DNA, as well as some operators and UI to present and manage the layers. For both the Alembic importer and the Cycles procedural, the main change is creating an archive from a list of filepaths, instead of a single one. After importing the base file through the regular import operator, layers can be added to or removed from the `CacheFile` via the UI list under the `Override Layers` panel located in the Mesh Sequence Cache modifier. Layers can also be moved around or hidden. See differential page for tests files and demos. Reviewed by: brecht, sybren Differential Revision: https://developer.blender.org/D13603
