feat(hal/usb): Make USB-DWC HAL&LL configuration independent

Browse Source 
Previously, we included symbols from soc/usb_dwc_cfg.h and configured
the HAL and LL according to it. Now we get the configuration in runtime
from USB-DWC registers.

Added missing definition for USB FS peripheral on ESP32-P4.
