Julien StJean 547c7f160d Optimisation to the legacy texture import and improvement to texture wrapper ...

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
