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.

This allows you to specify the exit scope amongst existing logging scopes, both in API and the CLI.
e.g for the CLI.
```bash
$ wazero run --hostlogging=exit,filesystem --mount=.:/:ro cat.wasm
```
e.g. for Go
```go
loggingCtx := context.WithValue(testCtx, experimental.FunctionListenerFactoryKey{},
logging.NewHostLoggingListenerFactory(&log, logging.LogScopeExit|logging.LogScopeFilesystem))
```
This is helpful to know if the wasm called exit or if it exited
implicitly. This is one of the few host functions that exists in three
places: assemblyscript, gojs and wasi.

This consolidates test files and ensures our various implementations of
`syscallfs.FS` pass `fstest.TestFS`.

This adds writefs.FS, allowing functions to create and delete files.
This begins by implementing them on `GOARCH=js GOOS=wasm`. The current
status is a lot farther than before, even if completing write on WASI is
left for a later PR (possibly by another volunteer).

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.
