Allowing device filter in the manifest for request port

Right now, The request port dialog is like this on Linux:

If the device filters are accepted i.e. with `usbVendorId` & `usbProductId` :
```
const filters = [{usbVendorId: 0x1a86, usbProductId: 0x7523}];
const port = await navigator.serial.requestPort({filters});
```

Request port dialog can be like this on Linux:

This setting can be useful for developers who support specific models of boards as device/vendor id doesn't change for a particular model and can reduce confusion for the end user.

Start by tracing how the manifest is read and how the request-port dialog calls navigator.serial.requestPort. Check how usbVendorId and usbProductId could be represented in the manifest and passed as filters, then verify that supported board selections show the filtered dialog without changing existing manifests.
