Use debugger in PlatformIO IDE over USB (no hardware needed) using openocd

[wsiok]

Please, use the following diff to enable debugger support in PlatformIO using openocd: In boards/lilygo-t-displays3.json replace existing openocd_target with: openocd_board": "esp32s3-builtin.cfg

In platformio.ini add in [env]:

debug_tool = esp-builtin
upload_protocol = esp-builtin

If the GSB single-stepping/breakpoint doesn't work because software breakpoint cannot be written (code executed from FLASH), then in the debugger console mark the code memory as read-only, for example: mem 0x40000000 0x4fffffff ro

Without these changes the openocd is run with incorrect interface and there are error messages about invalid command espusbjtag.
