[UX Design] KTX compression options in editor

Prototype and research what kind of KTX compression options we need to offer/can offer for designers in the editor tool based on Qt's asset conditioning enablers. Then implement that solution in the editor.

Expectation is that artist want to control the texture compression of content as texture compression has an impact to visual quality of the content. Thus some content may be compressed a lot without artefacts that have adverse impact, some content may have to be left uncompressed to get the visual quality that is needed.

On technical side we need an ".import" config file for textures that then controls what kind of compression options are used for the textures.
