Add progressive RemoteFX decode pipeline and wire it into the EGFX client and server: ironrdp-graphics: Progressive decode algorithms (first-pass and upgrade-pass coefficient reconstruction via SRL + inverse DWT), tile state tracking for multi-pass refinement, surface-level tile management with automatic quality progression. ironrdp-egfx: WireToSurface2 dispatch for progressive codec in GraphicsPipelineClient. Progressive surface state stored on the server for multi-pass frame scheduling.

The merged progressive primitives PR (Devolutions#1196) added validation that a ProgressiveRegion must contain at least one rectangle. The test used an empty rects vec which now fails decoding.
…c frames Add server-side progressive encode pipeline and multi-codec frame support: ironrdp-graphics: Progressive RFX encoder producing first-pass and upgrade-pass tile data via forward DWT + SRL quantization. Quality level control for adaptive bandwidth usage. ironrdp-egfx: send_remotefx_progressive_frame() for WireToSurface2 progressive transmission. MixedTilePayload enum and send_mixed_frame() for combining ClearCodec + Progressive RFX tiles in a single StartFrame/EndFrame pair.
