fix RHI upload of textures that are multiple of 4 in top mip but not in lower mips
dont pad CompressedImage sizes, store true size
clean up Texture size limits and VT conditions
better default settings for texture import
clean up initialization order of TextureFormatManagerModule

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.

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

-Add mechanism for ITextureFormat to have a generic and private "FormatSettings" block that can be global, but also exported with a texture build action and applied when a texture build is executed remotely. Also ensure that ChildTextureFormat is able to split and store/read the format settings for Child & Base format as separate sub-items.
-Allow the PS5TextureBuildWorker to compile in Oodle if the plugin is present and enabled.

This has a single use case: We build streaming virtual textures from runtime virtual textures and we want to ensure the format doesn't change just because the alpha channel is all 1.
