emnapi WebAssembly build

[toyobayashi]

I created emnapi for porting Node.js addons written in Node-API to Emscripten WebAssembly. I successfully built this project to wasm, all test cases passed except the one related to async_hooks, which is not supported by emnapi.

yarn node-pre-gyp configure --nodedir=./wasm --target_arch=wasm32
emmake yarn node-pre-gyp build --nodedir=./wasm --target_arch=wasm32
npx --arch=wasm32 yarn test

Update:

emnapi 0.28.1 has added the async_hooks support on Node.js. All test passed on my local machine.

Could you please enable CI for me?

Lines 3 to 6 in 88fd747

	const binding_path = binary.find(path.resolve(path.join(__dirname,'../package.json')), {
	target_arch: process.env.npm_config_target_arch || process.env.npm_config_arch || process.arch
	});
	let binding = require(binding_path);

not sure why npx --arch=wasm32 yarn test doesn't work in CI, seems node-pre-gyp find wrong binding path
