tools/testing/cxl: Expand CFMWS windows 



For the x2 host-bridge interleave windows, allow for a
x8-endpoint-interleave configuration per memory-type with each device
contributing the minimum 256MB extent. Similarly, for the x1 host-bridge
interleave windows, allow for a x4-endpoint-interleave configuration per
memory-type.

Bump up the number of decoders per-port to support hosting 8 regions.
