USB Host Stack not functional with UX_HOST_STANDALONE defined

[Ryzee119]

Describe the bug
The USB Host Stack does not function when trying to use it with UX_HOST_STANDALONE..

To Reproduce
Steps to reproduce the behavior:

1. Compile project with UX_HOST_STANDALONE
2. I happened to be using the OHCI backend but would be valid for any backend.

Some issues that I identified early in the device state machine:

_ux_host_stack_rh_port_reset does not return a UX_STATE value. So the status value is invalid here.

usbx/common/core/src/ux_host_stack_tasks_run.c

Line 535 in 331a669

status = _ux_host_stack_rh_port_reset(device);

‎_ux_host_stack_rh_port_reset‎ also returns UX_PORT_RESET_FAILED because it fails the check on actual_flags as _ux_host_event_flags_get is stubbed out.

usbx/common/usbx_host_controllers/src/ux_hcd_ohci_port_reset.c

Line 118 in 331a669

status = _ux_host_event_flags_get(&hcd_ohci -> ux_hcd_ohci_event_flags_group,

Not sure if this is intended to function with UX_HOST_STANDALONE or its for testing only?
