Fix compilation for unsupported platforms

[hybridherbst]

Currently, when compiling/building to some platforms, KtxUnity will error out:

Mostly with variations of

'KtxNativeInstance' does not contain a definition for 'INTERFACE_DLL'

This is not ideal; better would be that the platforms are explicitly unsupported but compilation would still work.

I tried setting the flags in the Runtime Ktx.asmdef:

But that brings follow-up errors in glTFast with it, so might not be as easy as that (there may be ifdefs needed in glTFast as well then).

To test compilation for all platforms, simply add https://openupm.com/packages/com.needle.compilation-visualizer to your project and put it into the testables in manifest.json, then run the editor tests seen in the screenshot above:

  "testables": [
    "com.needle.compilation-visualizer"
  ]

Fixed in KTX for Unity 3.3.0! Please transition to that package, as it is the official successor.
