cxl/region: Show access attributes once performance data is calculated

Region access attributes expose calculated latency and bandwidth to
userspace, allowing the performance of individual CXL regions to be
inspected independently of their use as system RAM.

Currently, attribute visibility is refreshed only when performance data is
propagated to a NUMA node. Regions whose memory is not onlined as system
RAM, such as pmem and devdax regions, can have valid performance data that
userspace cannot inspect.

Refresh attribute visibility when the region completes and its performance
data has been calculated. The existing visibility checks continue to hide
attributes without valid values, and NUMA node performance updates remain
unchanged.
