Previously the TinyUSB task was run in the ISR immediately after the
interrupt handler. This approach gives very similar performance (no change
in CDC throughput tests) but reduces the amount of time spent in the ISR,
and allows TinyUSB callbacks to run in thread mode.

For consistency with other board-level config macros that begin with
MICROPY_HW_USB.
Also allow boards in the mimxrt, nrf and samd ports to configure these
values.

The last argument of TUD_CDC_DESCRIPTOR() is the endpoint size (or
wMaxPacketSize), not the CDC RX buffer size (which can be larger than the
endpoint size).
