cannot import devicetree.edtlib for bossac runner

[2bndy5]

Describe the bug
Building off the solution for #37538, I'm finding that the bossac runner cannot import devicetree.edtlib, as evident from the warning generated by

zephyr/scripts/west_commands/runners/bossac.py

Lines 250 to 253 in 14d59b3

	if MISSING_EDTLIB:
	self.logger.warning(
	'could not import edtlib; something may be wrong with the '
	'python environment')

Manually installing the devicetree pkg fixed this problem

python -m pip install scripts/dts/python-devicetree

But I'm wondering if there is a more runner specific solution instead of manually installing the pkg.

To Reproduce
I'm using samples/basic/blinky targeting the adafruit_itsybitsy_m4_express
Steps to reproduce the behavior:

1. west build -b adafruit_itsybitsy_m4_express samples/basic/blinky
   

2. west -v flash --bossac='C:\Program Files (x86)\BOSSA\bossac.exe' --bossac-port='COM16'
   

   Notes:
   • -v is only used to get the trace back for the warning about not importing edtlib.
   • the path to the bossac.exe is using v1.9.1 x64 from official releases, but I also was able to use the executable shipped with the Adafruit Arduino core for the SAMD v1.7.1 (which seems to use bossac.exe v1.8.0-48-gb176eee)
3. Observe error via Python's trace back output.
4. Manually install the lib and repeat step 2

   python -m pip install scripts/dts/python-devicetree
   

5. Observe the led blinking on the board 🎉

Expected behavior
Since other modules in the scripts dynamically add the devicetree pkg to sys.path, I would expect the bossac runner to do something similar.

zephyr/scripts/dts/gen_defines.py

Lines 30 to 33 in 4f0cfdd

	sys.path.insert(0, os.path.join(os.path.dirname(__file__), 'python-devicetree',
	'src'))
	from devicetree import edtlib

But, maybe there's a more elegant solution.

Impact
Unable to flash programs using the bossac executable.

Environment (please complete the following information):

• OS: Windows (not using WSL, rather just using powershell)
• Toolchain Zephyr SDK 0.16.0
• Zephyr v3.2.99 with patch from scripts: runners: bossac: Enable BOSSAC to run on Windows (native) #53783

Additional context
The samples/hello_world seems to require extra config to enumerate the USB CDC serial device (for the adafruit_itsybotsy_m4_express), but I haven't delved into that. Not sure if that is even specific to the bossac runner; I'm still rather new to the zephyr project but I'm highly motivated to learn.
