feat(usb/host): Add option to choose peripheral for USB host library

Browse Source 
Starting with ESP32-P4 we can have targets that have more than 1 USB-OTG peripheral.
This commit adds an option to choose which peripherals will be used by USB Host lib.

Internally, we will still have only 1 Root HUB but with multiple Root ports.
