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 allows you to specify multiple logging scopes, both in API and the CLI.
e.g for the CLI.
```bash
$ wazero run --hostlogging=crypto --hostlogging=filesystem --mount=.:/:ro cat.wasm
```
e.g. for Go
```go
loggingCtx := context.WithValue(testCtx, experimental.FunctionListenerFactoryKey{},
logging.NewHostLoggingListenerFactory(&log, logging.LogScopeCrypto|logging.LogScopeFilesystem))
```

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 renames the internal writefs package to syscallfs as it is largely
dependent on syscall signatures. This also implements utimes in gojs.
WASI will be a follow-up change as it requires more infrastructure.
Notably, we also need non-TinyGo tests because TinyGo doesn't yet
support os.Chtimes or corresponding syscalls.

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).

`GOARCH=wasm GOOS=js` defines parameter names in go source, and they are
indirectly related to the wasm parameter "sp". This creates a pseudo
name section so that we can access the parameter names. The alternative
would be adding a hack to normal FunctionDefinition, only used for gojs.
