Can we decouple the (USE_HEXAGON_DEVICE STREQUAL "${PICK_HW}") and (USE_HEXAGON_RPC AND BUILD_FOR_ANDROID) cases into separate conditionals? It's a bit tricky to follow the flow and easy to make an error in the build for one or the other flows unintentionally when grouping them together like this.

See comment ⬆️ about breaking out not reusing the USE_HEXAGON_DEVICE block. It will also be easier to delete the USE_HEXAGON_DEVICE flow down the line if they are decoupled.

This will unconditionally add all files from that directory to the runtime target. If USE_HEXAGON_RPC is not set, it will cause link errors.

@kparzysz-quic thanks for pointing out. This could break if USE_HEXAGON_SDK and BUILD_FOR_ANDROID are enabled and USE_HEXAGON_RPC not enabled. So we should fix this. I suggest that we fix this with a cleanup of Hexagon.cmake once we agreed on using hexagon RPC and decided to deprecate hexagon proxy rpc and apps/hexagon_launcher.
