cxl/test: Give each mock memdev its own performance data

Assign distinct and predictable latency and bandwidth values to mock
memdevs so region performance calculations can be tested against the
expected contributions of individual targets.

Derive each memdev's performance data from its memdev id:
  latency   = 100 + 10 * id     (nanoseconds)
  bandwidth = 1000 + 100 * id   (MB/s)

These values allow tests to detect stale or duplicate contributions from
targets that are not members of the completed region. Since mock memdevs
are not PCI devices, the shared-upstream bandwidth calculation is skipped.
Region bandwidth in cxl_test will be the sum of the individual memdev
bandwidths, providing a predictable result for testing.
