[app][mdebug] version 1.0

- protocol now correctly reports SWO and SWCLK clock rates on set
- remove some debug printfs that were causing fw hangs (investigate later)
- allow setting a 1MHz SWCLK rate
- CMD_ATTACH now supports an argument to select one of several special
  reset or escape sequences:
  ATTACH_SWD_RESET: 60 HI, 4 LO, basic line reset
  ATTACH_JTAG_SWD: escape sequence for JTAG -> SWD mode switch
  ATTACH_DORMANT_TO_SWD: escape squence to exit dormant mode
  ATTACH_SWD_TO_DORMANT: and go back again
- add special support for writing to DP TARGETSEL register
  (response phase must be ignored), needed for SWD multidrop support
- bump protocol version to 1.3
- bump firmware version to 1.0 (it's long overdue)
