esp32/usb_serial_jtag: Flush usb_serial_jtag TXFIFO from ISR.
This was necessary to un-wedge the USJ TX path on ESP32-P4, I think because
the bootloader prints a lot on this chip. I think it might be possible to
hit it on other chips, though.
The implementation is based on the ESP-IDF driver, which will always add an
extra flush when the TXFIFO is empty in case the host is expecting a ZLP.
This work was funded through GitHub Sponsors.
