Oodle Texture has cutoffs for this internally but they're much lower; we're also using 16k pixels as the cut-off for CopyImage, seems like an OK target here.

These are important (and trivial) enough to warrant direct support.

Use TArray/TArray64 instead of raw allocs for our storage, there's no reason not to.
(The only reason the original code did raw allocs was because it was adapted from C code.)
Read from/write to memory not FArchive by request.
FDDSHeader->FDDSHeaderWithMagic, we don't care about the old-school DDSURFACEDESC,
we only ever have magic then ddsd so just make it part of the header struct.
Make mip sizes int64; a 16k * 16k R32G32B32A32_FLOAT image is enough to overflow 4GB.

to use Final EncodeSpeed on a texture instead of Fast when editing changes
so you can see the project's Final RDO settings while working on a texture

Put DDS parameter validation in one function (Validate) that is shared between Create, Read, Write funcs.
Add support for saving D3D9-format DDS files, either automatically when doing so is "lossless" in "Auto" mode, or in a D3D9-only mode that tries hard to express data as a D3D9 file and will fail when it can't find a suitable mapping. Still default to writing as D3D10-format DDS since that tends to preserve semantics the best.
The pixel format tables for D3D9-format DDS files were reordered slightly to make us prefer "canonical" choices when writing D3D9 DDS files, e.g. we prefer BC2 textures to get writtten as DXT3 not DXT2, and likewise BC3 should prefer DXT5 over DXT4.
