hongyi yu 97ca6811f1 Support duplicating non-optional mips in uptnl file, which will reduce IO seek time when loading textures with optional mips
- Since non-optional mips will be duplicated, this will increase build size
- Non-optional mips to be duplicated in uptnl files will be serialized twice when cooking, once in ubulk and once in uptnl
- Duplication can be controlled per LODGROUP in TextureLODGroups with attribute DuplicateNonOptionalMips
- When loading a texture with optional mips, if uptnl is available, all non-inline mips will be loaded from uptnl instead of from ubulk to reduce IO seek time and will improve performance
