Request: wasm support

[pdufour]

A bit of an unusual request, but is it possible to compile this to a wasm target? Didn't see any open issues about this. Thanks for the cool library!

Our recommendation if you're targeting web will be to target the DOM directly. Nevertheless, this is something we want to support. I have a patch which gets stylo compiling for WASM. Unfortunately that's currently causing issues with Gecko's bindings generation, so that will need to be sorted to land it, but if you wanted to try and get something working then you could use that branch.

@nicoburns am I right to assume that this is also blocked by linebender/parley#70?
