Tested cooked build diff for sanity as this should only ever affect in-memory editor values.

TextureFormatOodle : yes you can free the float mip immediately because hashing is no longer on an async task
FImage::FreeData with async detach option
validate VT sizes better to prevent crashes

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.
