change FImage passed to TextureFormat to be const, it must not be changed becausing hashing is running threaded
remove early frees of intermediate image; this increases peak memory use

Plumb the mip layout down to the child texture ddc key versions as certain child formats need to know mip dimensions in order to know if aspects of the build affect the textures.

Certain platforms that tile textures will tile non pow2 textures with mips different than non pow2 textures without mips, so we need to plumb down information about the mip chain to the tiling texture formats.

TextureFormatOodle is the only format that returns true for CanAcceptNonF32Source(), which allows the build system to occasionally avoid converting to an F32 input to the compressor. However, the ChildTextureFormat for offline platform processing did not forward this function so this conversion was happening unnecessarily.
This manifested as a DDC determinism issue with the PreEncodeHash when enabling shared linear encoding, where the output mip data would be the same (as the F32 conversion would round trip without change), however the input to the convertor would change between platforms.
Since Oodle is the only format that routes this, we can invalidate only this format and avoid a worldwide rebuild.

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]

This is necessary to support building textures independently of the UTexture, which is required by the new derived data build interface.

-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.
