RDMA/core: Expose Completion Counter capabilities to userspace
Add a dedicated query interface for completion counter capabilities
via UVERBS_METHOD_QUERY_COMP_CNTR_CAPS on the device object.
The query returns the maximum number of counters, maximum counter
value, and a bitmask of supported QP attach operations. Each field
is an optional ioctl attribute, allowing userspace to request only
the capabilities it needs.
Drivers implement the query_comp_cntr_caps operation to report
device-specific capabilities.
