Delegate all fs operations to WASI host in wingc

[MarkMcCulloh]

Currently we use WASI to read/write files from within wingc. This is convenient, but brings challenges. It also limits us to requiring WASI rather than being able to run in pure WASM contexts.

Most challenges are due to dealing with preopens which have to be posix paths, thus causing issues with Windows.

Proposal: From rust, call into extern JS function for fs operations. Similiar to how this is used.

The "business" impact might be that windows or other OS might break more easily

It's also a stability issue - we rely on WASI, which is experimental, instead of directly on WASM (which is not experimental)
