Add support for VHCA_ID-based page management mode. When the device firmware advertises the icm_mng_function_id_mode capability with MLX5_ID_MODE_FUNCTION_VHCA_ID, page management operations between the driver and firmware may use vhca_id instead of function_id as the effective function identifier, and the ec_function field is ignored. Update page management commands to conditionally set ec_function field only in FUNC_ID mode. Boot page allocation always uses FUNC_ID mode semantics for backward compatibility, as the capability bit is only available after set_hca_cap(). If after set_hca_cap() VHCA_ID mode was set, modify the tracking of the boot pages in page_root_xa to use vhca_id too. Add mlx5_esw_vhca_id_to_func_type() to resolve the function type in VHCA_ID mode, enabling per-type debugfs counters. Use a dedicated vhca_type_map xarray, to provide lockless lookup. Store the resolved type on each fw_page at allocation time so reclaim and release paths read it directly without any lookup.
