Cache TextureFormat on the BuildSettings so we don't have to look through the TPM whenever we want it.

1. Whether the source mips detects alpha
2. Several hashes to track the state of data at various stages of the build process.
Move the r.SharedLinearTextureEncoding out of the ConsoleManager as that's The Old Way.
Rename TextureDerivedDataVersion for uniqueness.

This allows for pausing of async texture compilation and limiting concurrent texture builds based on the same memory limits that the asset compiling manager uses.

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

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

Headers are updated to contain any missing #includes needed to compile and #includes are sorted. Nothing is removed.

This allows faster texture cooking, but introduces slight changes to newly computed pixel values.
Quality of texture mips stays the same, but values are different due to different order of floating-point operations.
To keep patch sizes small, use old same code as before for generating mips for existing textures - will use new filter only for saved textures.
Currently this setting is disabled for new textures by default. See comment in Texture.cpp how to enable it.

FImage is now the standard preferred type for a bag of pixels
FImageView can point at pixels without owning an allocation
ERawImageFormat (FImage) converts to ETextureSourceFormat
FImageUtils provides generic load/save and get/set from FImage
major cleanup in the ImageWrappers
new preferred API is through ImageWrapperModule Compress/Decompress
SetRaw/GetRaw functions cleaned up to not have undefined behavior on unexpected formats
ImageWrapper output added for HDR,BMP,TGA
RGBA32F format added and supported throughout import/export
EditorFactories import/export made more generic, most image types handled the same way using FImage now
Deprecate old TSF RGBA order pixel formats
Fix many crashes or bad handling of unusual pixel formats
Pixel access functions should be used instead of switches on pixel type

Wasn't doing anything useful
It actually converted any non-zero alpha to full opaque
almost the opposite of what it claimed to do
Simplify the option set by removing useless options rather than fix it

AlphaCoverageThresholds was accidentally enabled for all textures with thresholds = {0,0,0,1}
add new Texture bool bDoScaleMipsForAlphaCoverage
to make toggling coverage processing very clear
on old Textures that don't have the bDoScaleMipsForAlphaCoverage field, we can infer the correct value except in the case that threshold = {0,0,0,1} , in that case it's impossible to tell if it's wanted or not. There we look up a config value "EnableLegacyAlphaCoverageThresholdScaling"
Current config has EnableLegacyAlphaCoverageThresholdScaling=1
so the legacy bad behavior is maintained
