Support `stampinf` passthrough in `cargo-wdk`

`cargo-wdk` hardcodes the `stampinf` invocation during the packaging phase.

Current invocation
```
stampinf -f <pkg>\<name>.inf -d * -a <arch> -c <name>.cat [-v *] [-k <maj>.<min> | -u <maj>.<min>.0]

NOTE: -v * is omitted when the STAMPINF_VERSION env var is set to a non-empty value.
```

Add `--stampinf-args` to support to customize `stampinf` options.
