Fix KiCad WASM build and runtime errors

Browse source 
Build improvements:
- Change -O0 to -O1 to fix "local count too large" asyncify error
- Add wasm-emscripten-finalize to host (Docker OOMs on large WASM)
- Use -gseparate-dwarf for smaller main binary with debug info
- Build native protoc for code generation
- Add more functions to asyncify removelist

Runtime fixes:
- Add inject-dyncall-shims.sh to fix "dynCall_* is not defined" in Emscripten 4.x
- Update wxwidgets with browserInfo.name fix

New stubs and bindings:
- Add Embind bindings for JavaScript interop
- Add stubs for scripting, API plugin, PCB frame, navlib
