Dan Thompson f3d53d2ba3 Fix for mip generation for child platforms unnecessarily linearizing. ...

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.
