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
Closes https://github.com/espressif/esp-idf/issues/7786
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.

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
