b891aa0443 usb_host: Refactor USBH and USB Host Library calls to HCD
This commit refactors the USBH and the USB Host Library in the following ways:

- USBH now presents an abstraction of an endpoint (via usbh_ep_handle_t)
    - Added separate functions to enqueue/dequeue URBs to a particular endpoint
    - USB Host Library no longer calls HCD API directly. Calls USBH endpoint API
      instead.
- Renamed "notif_cb" to "proc_req_cb" (Processing Request Callback)
    - This is to avoid confusion with FreerTOS task notifications and Host
      Library client event notifications.
    - The processing functions of each layer (i.e., "xxx_process()") request
      calls via the "proc_req_cb"
    - The main handling function (i.e., usb_host_lib_handle_events()) is
      responsible for calling the required "xxx_process()" of each layer

27078ac34c usb_host: Fixed incorrect opening devices from multiple clients
1. During USBH device open both queues (idle and pending) must be checked.
2. Don't overwrite already allocated endpoints

22c152c388 usb: Hub Driver and USBH recover port automatically after disconnection
This commit updates the Hub Driver and USBH as follows:
- Updated communication mechanism between Hub Driver and USBH
    - USBH notifies the Hub Driver via Hub request callback (usbh_hub_req_cb_t)
    - Hub Driver notifies the USBH via usbh_hub_pass_event()
- Hub Driver now defers all event handling to hub_process.
- Hub Driver and USBH will now automatically recover the port after a disconnected
    device has been closed.
- Fixed incorrect assert in usbh_dev_close()

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

189899180f usb: Change API and refactor tests
This commit updates the USB Host Library API in the following wasy:
- usb_host_client_handle_t and usb_device_handle_t made into struct pointers
  to generate compiler warnings about conflicting handle types
- usb_host_client_config_t changed to future proof API for Synchronous Clients
- Added usb_host_lib_unblock()
- Added usb_host_device_addr_list_fill()
- Return of usb_host_device_free_all() updated to indicate whether there
  are still devices yet to be freed.
- Blockg APIs are now marked explicitly
- Fixed a bug in usb_host_transfer_submit_control() when checking the bEndpointAddress
  of a control transfer.

Tests are also refactored to move some common macros into shared headers

6a12e28333 usb: Fix USBH handling of disconnections
This commit fixes how the USBH handling of a sudden device disconnection,
more specifically handling of device gone.
- Previously the USBH would only halt, flush, and dequeue the device's
default EP, then send a device gone event to the Host Library layer.
- Now the USBH will also halt and flush all non-default EPs, allowing
all of the URBs to be dequeud.
- Some internal object members are now protected by a mutex instead of
a spinlock.

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
