JS: Build with threads and gdnative where supported

Classical builds now use Emscripten 2.0.10 and have threads and gdnative
templates.

Mono builds still use Emscripten 1.39.9 for compatibility with Mono 6.12.x, so
they cannot have GDNative support which requires 2.0.10+. And threads build
triggers wasm-ld errors without LTO, and wasm-ld crash with LTO, so no dice
there either.
