Refractor

- Added Initialize() function to TextureCache and AutoDeleteCache
- Removed GetMaxTextureCapacity() function and instead added _maxCacheMemoryUsage
- Added private const MaxTextureSizeCapacity to AutoDelete Cache
- Added TextureCache.Initialize() to MemoryManager in order to fetch MaxGpuMemory at the right time.
- Moved and Changed Logger.Info for Gpu Memory to Logger.Notice and Moved it to PrintGpuInformation function.
- Opted to use a ternary operator for the Initialize function, I think it looks cleaner than bunch of if statements.
