feat(schema-wasm): support environments other than Node.js

Previously we generated wasm-bindgen bindings for
`@prisma/prisma-schema-wasm` with `--target nodejs`. This makes the
generated glue code use Node.js `fs` module to load the WebAssembly
module from disk and then instantiate it from an array of bytes.

This commit change this to `--target bundler` which is what we use for
`query-engine-wasm`. This makes wasm-bindgen use `import` statement to
load the WebAssembly module instead.

This is a breaking change, and requires updating Prisma CLI and language
tools.
