esp_usb_jtag: new cable

- copy dirtyjtag to esp_usb_jtag, it compiles
- copy protocol definiton, defines and private data/struct from openocd esp_usb_jtag.c
- ulx3s_esp board with esp32s3 cable
- esp_usb_jtag specify usb vid:pid in jtag.cpp
- hardcode usb interface and endpoints
- getting caps
- set chip id (not applicable for fpga)
- tms write done, untested
- cleanup and toggle clk
- 32bit counting
- setting divisor (todo read base freq)
- div range within 1-255
- base speed from descriptor
- fix doc typo with swapped tms/tdi some cleanup but it doesn't work.
