1aad12468a usb: Hub Driver Update and Refactor
Hub Driver is refactored as follows:

This commit update and refactors the Hub Driver as follows:

- Refactored enumeration state machine and stage functions
    - Enumeration stage is now incremented
    - Combined transfer stages of enumeration into common functions
- Comments updated
- Fixed usbh_hal_disable_debounce_lock() that would cause root_port_handle_events()
    to fail the HCD_PORT_CMD_RESET call because the previous port connection interrupt
    was not cleared.

The following features were added to the Hub Driver

- Enumeration config descriptor is now fetched in two separate stages
    - Header is fetched first to determine the wTotalLength of the descriptor
    - Fetching the full descriptor will request exactly wTotalLength bytes
    - This works around some non-compliant devices that will babble/return zero
        when requesting a length > wTotalLength
    - Closes https://github.com/espressif/esp-idf/issues/7799
- Enumeration now stores string descriptors
    - The Manufacturer, Product, and Serial Number string descriptors are
        now read and stored during enumeration
    - String descriptors are now part of usb_device_info_t
- Added unit test to test enumeration

854127a57c usb: USB Host stack uses USB PHY driver
This commit updates the USB Host stack to use the USB PHY driver. The
USB PHY and the OTG Controller should now both be setup/deleted using
usb_new_phy() and usb_del_phy() respectively.

- The hcd_install() now expects the USB PHY and OTG Contorller to be
    already setup before it is called
- usb_host_install() now has an option to skip calling usb_del_phy() if
    the user wants to setup their own USB PHY (e.g., in the case of using
    and external PHY).
- CDC-ACM and MSC examples/test updated to use internal PHY

Closes https://github.com/espressif/esp-idf/issues/8061

accbaee57c Add USB Host Library
This commit adds the preliminary version of the USB Host Library. This commit contains:

- USBH (USB Host Driver)
- Hub Driver that only supports a single device and device enumeration
- USB Host Library (asychronous API)
- Test cases for USB Host Library asychronous API

The following changes were made to the existing HCD:
- Removed HCD_PIPE_STATE_INVALID. Pipes are no longer invalidated
- Changed pipe commands to halt, flush, and clear. Pipes need to be manually
  halted, flush, and cleared.
- Halting and flushing a pipe will execute the pipe callback if it causes a
  HCD_PIPE_EVENT_URB_DONE event

b901cbd273 USB: Make unit test mock classes common
This commit moves the mock classes used for HCD unit tests into
a common header so that other layers of the USB Host stack can
also utilzie them for their own unit tests.
