T
Qing Tao 9fac26e6a6 Update o3de to use new packages of ISPCTexComp and squish-ccr (#3556) 
Update package name and hash
Add compressor names.
Update ImageProcessingAtom unit tests.
Removed some unused test assets under ImageProcessingAtom
Enalbe ISPC to all the platforms.
Better error message with compression/decompression
Add temp folder to git ignore
added ispccompressor for all platform. valid it with linux
Update windows package hashes.
Removed AZ_TRAIT_IMAGEPROCESSING_USE_ISPC_TEXTURE_COMPRESSOR
Minor refactor with image processing unit tests.
