Extends the link state control feature to CDC-ECM mode.
RNDIS mode prints state changes but doesn't send notifications
to the host yet (would require RNDIS_INDICATE_STATUS_MSG).
For ECM:
- Tracks link state and sends proper CDC notifications
- Handles notification endpoint busy conditions
- Only sends connection notification when link is actually up

This adds the ability to dynamically control the network link state
for NCM devices. The host OS will see the network interface as
connected/disconnected based on the link state.
New API:
- tud_network_link_state(rhport, is_up): Set link up/down state
Example updates:
- Added button control to toggle link state
- Fixed LWIP integration to properly handle link state changes
- Added printf to show correct protocol (NCM vs RNDIS/ECM)

TinyUSB does not provide any locking means to protect the DCD variables.
This can lead to race conditions when the user is trying to submit
a transfer while the device is being disconnected. This can cause
the device to be in an inconsistent state, leading to a crash or
undefined behavior.
This commit adds a spin-lock to protect the DCD variables during
device disconnect.

hub: add hub_port_get_status_local(), ignore resp in hub_port_get_status(pot != 0)
usbh properly deboucning with hub/rootport accordingly to usb specs, also add 10ms of reset recovery
replace dev0.enumerating by enumerating_daddr for better clean up on unplugging while enumerating
move controller_id & enumerating_daddr into _usbh_data struct
- if a previous enumeration failed _ctrl_xfer status could stuck, it needs to be cleared before next attempt.
- after _dev0.enumerating is reset in hcd_event_handler(), if an attach event arrived before _ctrl_xfer clean up in remove event, a racing condition will happen.
