Adds support for the 'flash' command to the jlink runner so we can flash
via 'make flash'. This works by generating a temporary jlink commander
script file and passing the script to the jlink commander executable.
Previously, the only way to flash with jlink was via 'make debug'.
Includes support for DT based flash address, and an optional mass erase
before loading the flash.

The various runners (flash/debug scripts) use environment variables to
take arguments. This is legacy behavior which is not desirable.
Use command line arguments instead.
Note: this leaves more general environment variables with publicly
documented behavior in place for now, for compatibility, e.g.:
ZEPHYR_FLASH_OVER_DFU, OPENSDA_FW, ESP_IDF_PATH, PYOCD_DAPARG
For example, when using dfu-util to flash arduino_101, instead of
setting DFUUTIL_PID, DFUUTIL_ALT, and DFUUTIL_IMG environment
variables, have the script invocation look like this:
python3 .../zephyr_flash_debug.py dfu-util flash \
[common arguments omitted] \
--pid=8087:0aba --alt=x86_app \
--img=.../build/zephyr/zephyr.bin
Make similar changes for other runners (openocd, etc.) and
targets (debug, debugserver).
To implement this in the scripts:
- have the individual scripts/support/runner/some-runner.py files
register their own command line arguments
- teach them to construct instances from arguments, not the
environment
- have zephyr_flash_debug.py request runners to register command
line argument parsers, and handle arguments
In the build system:
- add a new board_runner_args() extension function that board.cmake
files can use to add to the zephyr_flash_debug.py command line
- adjust cmake/flash/CMakeLists.txt to invoke with arguments
- add new helper include files for each runner (like
boards/common/dfu-util.board.cmake, etc.), which add default
options as needed and then add on overrides from
board_runner_args() calls
- update board.cmake files to use the new includes and extension
This implied some tweaking when using openocd to make the CMake string
escaping and unescaping work properly.
