Script that can find programmer and flash firmware via it. (#2193)

* Init
* Fallback to networked interface
* remove unneeded cmsis_dap_backend
* serial number
* windows :(
* remove jlink, fix path handling
* scripts: program: path normalization
* scripts: program: path normalization: second encounter
