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.

1. Whether the source mips detects alpha
2. Several hashes to track the state of data at various stages of the build process.
Move the r.SharedLinearTextureEncoding out of the ConsoleManager as that's The Old Way.
Rename TextureDerivedDataVersion for uniqueness.

don't change existing content, only normalize when new option bNormalizeNormals is enabled
note that ISPCTexComp is inconsistently doing normalization, no other tex formats do
