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 changes the listener signature to accept context and calling
module, so that all possible parameters and results can be logged. This
also changes the logging listener to make parameters visible when
logging results.
This infrastructure supports some helpful use cases, such as logging
WASI result parameters, such as the prestat path, which is only knowable
after the function has been called. The context parameter supposed
reading results of gojs functions, which are stored host-side in a go
context object.
Future pull requests will complete this as well backfill unit tests.
This is raised independently mainly to keep the PR size down of the
upcoming filesystem logger.

This makes it easier to do maintenance by hiding the implementation
details of using a proxy module to test host modules. What happens is we
skip logging of these proxy modules, which makes it easier to see what
log affects a change has.

This switches to gofumpt and applies changes, as I've noticed working
in dapr (who uses this) that it finds some things that are annoying,
such as inconsistent block formatting in test tables.
