Damien George 1e4849557d esp32/usb: Further improve speed of USB CDC output.
Following on from ba940250a5, the change here
makes output about 15 times faster (now up to about 550 kbytes/sec).

tinyusb_cdcacm_write_queue will return the number of bytes written, so
there's no need to use tud_cdc_n_write_available.

Seon Rozenblum 35fb90bd57 esp32/usb: Add USB host connection detection for CDC serial output.
This callback allows detecting if there is a USB host connected to the CDC
or not, in which case the stdout_tx should skip CDC TX writing and
flushing or the system will block.

Fixes issue #7820.
