feat: include serial number in list-ports output

[vfabr]

The current list-ports output lacks serial numbers, making it impossible to identify specific devices when multiple ESP32 are connected and now it is possible to get a port for the flash by PROBE.

$ probe-rs list  
The following debug probes were found:
[0]: ESP JTAG -- 303a:1001:B4:3A:45:AE:52:FC (EspJtag)
[1]: ESP JTAG -- 303a:1001:B8:F8:62:FC:17:8C (EspJtag)
$ espflash list-ports
/dev/ttyACM0  303A:1001:B4:3A:45:AE:52:FC          Espressif  USB JTAG/serial debug unit
/dev/ttyACM1  303A:1001:B8:F8:62:FC:17:8C          Espressif  USB JTAG/serial debug unit

Thanks for the contribution! I think it makes sense to add this information, but maybe on a different format? For USB-Serial/JTAG the format is good but for UART ports:
/dev/ttyUSB0 10C4:EA60:dc414a793059ed11a99bb5301d62bc44 Silicon Labs CP2102N USB to UART Bridge Controller

My problems are:
I wanted to get ability

• to distinguish between several connected boards
• to use a single one UNIQ for work with boards (run tests, flash firmware, flash storage, get additional info etc.)
  and representation like 303A:1001:B4:3A:45:AE:52:FC looks compatible with the probe-rs output

It seems JTAG serial_number based on MAC address and hardware burned into chip but USB_to_UART_Bridge may not have it or have the same. I've tried a few boards with USB and it looks like serial_number is not good choice here.

It looks indistinguishable

/dev/ttyUSB0  10C4:EA60:0001                       Silicon Labs  CP2102 USB to UART Bridge Controller
/dev/ttyUSB1  10C4:EA60:0001                       Silicon Labs  CP2102 USB to UART Bridge Controller

but interesting that Linux have the same problem

$ ls -la /dev/serial/by-path/
pci-0000:00:14.0-usb-0:5.3.1:1.0-port0 -> ../../ttyUSB1
pci-0000:00:14.0-usb-0:5.3.2:1.0-port0 -> ../../ttyUSB0

$ ls -la /dev/serial/by-id/
usb-Silicon_Labs_CP2102_USB_to_UART_Bridge_Controller_0001-if00-port0 -> ../../ttyUSB1

$ ls -la /dev/ttyU*
/dev/ttyUSB0
/dev/ttyUSB1

compare with JTAG

$ ls -la /dev/serial/by-path/
pci-0000:00:14.0-usb-0:5.3.1:1.0 -> ../../ttyACM1
pci-0000:00:14.0-usb-0:5.3.2:1.0 -> ../../ttyACM0

$ ls -la /dev/serial/by-id/
usb-Espressif_USB_JTAG_serial_debug_unit_8C:D0:B2:A9:36:78-if00 -> ../../ttyACM0
usb-Espressif_USB_JTAG_serial_debug_unit_8C:D0:B2:A9:3F:5D-if00 -> ../../ttyACM1

$ ls -la /dev/ttyA*
/dev/ttyACM0
/dev/ttyACM1

I don't see any good solution for USB except to use MAC address for this aims. But it can be more complicated ... and I know nothing about the previous and next esp generations WROOM or P4 because I don't have it :))

For my current aims this is a good enough solution because I use only JTAG boards now. But I agree that could be more common and better implementation here. I need more time to try to do it :)
