Unable to init stack on two ports simultaneously.

Relates to:

• Support two physcial host ports on the RP2040 (native and pio) #1673 (comment)

Describe the solution you'd like

Possibility to run TinyUSB (device) stack on several peripherals (ports) simultaneously.

In the code that would be like:

tusb_rhport_init_t dev_init = {
  .role = TUSB_ROLE_DEVICE,
  .speed = TUSB_SPEED_AUTO
};

tusb_rhport_init(0, &dev_init);
tusb_rhport_init(1, &dev_init);

I have checked existing issues, dicussion and documentation

I can try to get host stack running on multiple controllers (same usbip) easily. For device, it needs quite a bit of works, and it is kind of neat and not popular feature. I am not sure Icould mannge the time to do it myself, however PR is welcome.
