Switch BrowserWasm from Blazor AOT to NativeAOT-LLVM

Replace Microsoft.NET.Sdk.WebAssembly with Microsoft.NET.Sdk and
PublishAot/IsAotCompatible. Strip all Blazor-specific properties
(RunAOTCompilation, WasmBuildNative, WasmStripILAfterAOT, WasmRunWasmOpt,
size-reduction flags). Same AOT pipeline as Motely.NodeAddon now.
