Subject: Implement R16S & R16UI & R16I RenderTargetFormats & PixelFormats and
 more (R16_UNORM needed by Fate Extella) (#848)

* Implement R16S & R16UI & R16I RenderTargetFormats & PixelFormats


Do a separate function in order to get Bytes Per Pixel of DepthFormat


Apply the new function in gpu.h


delete unneeded white space

* correct merging error
