CXL Dynamic Capacity Device (DCD) support is being discussed in the
upstream kernel. cxl-cli requires modifications to interact with those
devices.
A new partition type 'dynamic_ram_a' has been added which cxl-cli
needs to know about. Add support for the new decoder type.
With DCD regions may, or may not, have capacity. The capacity is
communicated via extents. Add region extent query capabilities.
Add cxl-test support. cxl-testing allows for quick regression testing
as well as helping to design the cxl-cli interfaces.
