Add support for building for Windows ARM64 devices

[anthony-linaro]

Description of Change(s)

Add support for Windows ARM64 devices.

This was tested using the following command line:

python build_scripts/build_usd.py --no-python --onetbb --tests --no-imaging C:/WoA/OpenUSD/build_dir

Python is currently switched off due to lack of support for PySide on these devices. I am looking at that seperately.

I also had to disable imaging, as building boost appears to be broken when using newer CMake versions (similar issue to #3285)

TBB is set to OneTBB, as 2020u3 doesn't support these devices.

I also had to make a small modification in testWrapper.py, and change line 134 to pathPattern = pathPattern + r'(\S*)', as otherwise the escape sequence was invalid.

Any reason why the testWrapper.py change you mentioned isn't included here? Otherwise, lgtm

I figured it was more related to the version of python I have installed (3.12.5), rather than the one used for validation on other devices - as I didn't have those devices/versions to hand, and knew the script already worked as-was on them, I opted not to change it
