This adds `gojs.WithOSUser` which passes through current user IDs so
that GOOS=js compiled wasm can read them. This also adds support for
reading back the uid and gid on files. In summary, this passes
`os.TestChown` except on windows where it will not work due to lack of
support.

In order to support more configuration, we should stop using context as
it is getting gnarly.

Many tests failed in gojs due to needing to be resolved against the CWD,
which is atypically stored host side. This fixes that and renames the
"exit" scope to "proc" so we can use it for other proc concerns besides
exit.
This reduces known failures on GOOS=js from 23 to 14:
```bash
$ wazero run -mount=/usr/local/go/src/os:/:ro -mount=/tmp:/tmp -mount=/etc:/etc:ro -mount=/usr:/usr:ro -mount=/dev:/dev:ro os.wasm |grep '^--- FAIL'|wc -l
14
```

This avoids logging activity on stdio file descriptors, in order to help
make troubleshooting easier. Usually, there isn't an issue in these, yet
wasm panics are harder to read if there is also logging of the ..
logging.

This stubs all remaining syscalls for `GOARCH=wasm GOOS=js` to return
ENOSYS, instead of panic'ing. This allows us to see the parameters it
receives.
For example:
```
==> go.syscall/js.valueCall(fs.truncate(path=/tmp/_Go_TestTruncate135754730,length=0))
<== (err=function not implemented,ok=false)
```

This refactors GOOS and GOARCH specific code into their own packages.
This allows logging interceptors to be built without cyclic package
dependencies.

This adds an experimental package gojs which implements the host side of Wasm compiled by GOARCH=wasm GOOS=js go build -o X.wasm X.go
This includes heavy disclaimers, in part inherited by Go's comments https://github.com/golang/go/blob/go1.19/src/syscall/js/js.go#L10-L11
Due to this many will still use TinyGo instead.
That said, this is frequently asked for and has interesting features including reflection and HTTP client support.
