[roll] Roll fuchsia [usb] Create usb-phy fidl metadata

Create the fuchsia.hardware.usb.phy.Metadata FIDL type. Replace the
usage of the `UsbPhyMode` and `PhyType` C++ types defined in the
//src/devices/lib/amlogic library with this new FIDL type.

Currently this metadata is sent between drivers using the driver compat
server. The compat server is planned on being removed. Now that the
metadata is defined in FIDL, a future CL can update these drivers to
send the metadata using the //sdk/lib/driver/metadata/cpp library.
