net/mlx5: ICM page management in VHCA_ID mode

This series adds driver support for the VHCA_ID page management mode.
When firmware and driver support this mode, ICM (Interconnect Context
Memory) page management uses the device vhca_id as the function
identifier in MANAGE_PAGES, QUERY_PAGES, and page request events instead
of the legacy function_id + ec_function pair.

Background
Firmware can operate page management in two modes:
FUNC_ID mode (current): Function identity is (function_id, ec_function).
This remains the default and is used for boot pages and when the new
mode capability is not set.
VHCA_ID mode (new): Function identity is vhca_id only; ec_function is
ignored. This aligns page management with the vhca_id-based model used
by other firmware commands and simplifies identification on SmartNIC and
multi-function setups.
