Fix WebAssembly support

Browse source 
There was a problem in the upstream `sys-locale` crate where it assumed
that every WebAssembly target can use `wasm-bindgen` just fine. This
however is not the case, as `wasm-bindgen` and the ecosystem around it
are specifically to target the web. In reality there however are at
least the following 4 "targets" (with possibly more in the future):
 - WebAssembly on the web
 - Freestanding WebAssembly
 - WebAssembly with WASI
 - WebAssembly with Emscripten

These are all supported properly through `sys-locale` 0.3.0 now. However
because "WebAssembly on the web" unfortunately is not its own target and
instead uses `wasm32-unknown-unknown`, just like freestanding
WebAssembly, the only way to differentiate between them is through a
feature. This is the best practice and is done throughout the ecosystem.
Here the feature `wasm-web` is introduced that properly forwards it to
`sys-locale` and possibly other crates in the future.
