Library bundle with inlined WASM fails in Node < 16

[pastelmind]

Describe the bug

A library (built with build.lib) with inlined WebAssembly (.wasm) files fails in Node.js < 16. This is because the Vite-generated bindings use atob(), which is available only in Node.js 16+.

The binding code is:

vite/packages/vite/src/node/plugins/wasm.ts

Lines 9 to 18 in d402ad3

	if (url.startsWith('data:')) {
	// @ts-ignore
	const binaryString = atob(url.replace(/^data:.*?base64,/, ''))
	const bytes = new Uint8Array(binaryString.length)
	for (let i = 0; i < binaryString.length; i++) {
	bytes[i] = binaryString.charCodeAt(i)
	}
	// @ts-ignore
	result = await WebAssembly.instantiate(bytes, opts)
	} else {

Although Vite is primarily geared towards web browsers, Vite's Library Mode is useful for developing isomorphic libraries that must support browsers and Node.js. Since Node.js v14 has plenty of time to reach EOL (due April 2023), it would be great to support it.
