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

Unfortunatly it doesn't support the old jpeg format yet. Not sure why currently, but modern tiff encoded using jpeg are fully supported.

- When libjpeg-turbo is enabled we now disable libJPG, before we were including both and relying on libJPG being stripped out.
- Fixed IcoImageWrapper.cpp to compile if WITH_UNREALPNG is 0.
- Cleaned up code comments around enabling libjpeg-turbo with a reminder to investigate the exe size increase if anyone tries to enable it on a console platform.

Changed the texture payloads so that they use the new unique buffer.
Refactored the blocked texture payload and the UDIM translator to support the new payload.
Added some functions to the FTextureSource so that it can receive a FSharedBuffer instead of copying the data into the payload.
Removed the const requirement from the UInterchangeFactoryBase main functions. It was needed so that I can store the texture payload in the function CreateAsset and then consume it in the function PreImportPreCompletedCallback. Also reporting messages in the factory does affect the state of the factory.
The Interface IImageWrapper has a new function to get the raw data into an ArrayView. For now the interface provides a default implementation but I would like to make it abstract when all the existing wrapper will have an implementation for it.

Adding support of hdr to interchange those are now imported as standart 2d Texture.

Minor change to FImageWrapperBase. GetRaw and GetCompressed now consume the array with the same name instead of having to do a copy of it.
I changed the api IImageWrapper::GetCompressed to return a TArray64<uint8> instead of returning a const TArray64<uint8>&.
Added the format RGBAF to the struct ERGBFormat. Changed the engine code using the EXR image wrapper to reflect that.
The EXR image wrapper now avoid doing an unessary copy of the compressed image when calling compress.
Improvement to the performence of the function UTextureFactory::ImportImage. We now use the magic bytes of the file for certains format to skip some tests.
Here is some performance metrics I captured on my desktop (6 core, 12 threads XEON)
Importing a folder of tiff files (22 files, 4.16 GB Total)
Before: 66.152738 seconds
After: 43.609245 seconds
