8b4692d085 Remove "mutable" parts of the build settings. For platforms that need the mip dimensions, this is now piped down via a parameter instead of violating "const".

7b03388528 Normal Maps were not renormalizing normal vectors after generating mips 
caused reduced length normals, which then bends them when we drop components for compression in BC5 or ASTC
don't change existing content, only normalize when new option bNormalizeNormals is enabled
note that ISPCTexComp is inconsistently doing normalization, no other tex formats do

b66139e721 Shared Linear Texture Encoding [DDC2] -- Separates out the platform tiling code to allow for texture builds to reuse the linear texture that gets encodes with windows. 
Primary Components:
    DDC2 texture build input/output revamped to support future FDerivedData references where the bulk data remains in the Zen server during cooks.
    Tiling code is separated out in to ITextureTiler interface so that tiling can be done without calling FChildTextureFormat::CompressImage[Ex]
    Adding mip dimensions to GetMipCountForBuildSettings

3052881f21 Fix Editor crash when performing texture downscaling with specific parameters and texture size. 
Note: the crash occured in cases when the scaled dimensions snapped to zero. For example, when the source dimensions are (blocksize * p) and (blocksize * q), where p and q are coprime and downscaling factor scales the dimensions more than twice (considering the rounding).
