cxl/test: Add cxl_test accelerator driver

This commit adds a mock platform driver simulating a CXL type 2 accelerator
device. It is designed to test minimal API calls required by real CXL type 2
drivers.

[Severity: Low]
Are the cxl_set_capacity and devm_cxl_probe_mem functions defined anywhere in
the kernel source tree?

It appears these functions do not exist, which causes an implicit declaration
error and undefined references during compilation. Will this lead to an
immediate build failure for the test module?
