cxl/test: Define a CFMWS capable of a 3 way HB interleave

The CXL unit test cxl-xor-region.sh is skipping a 1+1+1 region
interleave test case because the window is not defined.

Additionally, upcoming expansion of 3 way HB interleave test cases
(like 2+2+2) require the same window.

Replace an unused CFMWS with a 3-way capable CFMWS in the set of
CFMWS's loaded when interleave_arithmetic=1.
