ice: add Tx reference clock index handling to AN restart command

Extend the Restart Auto-Negotiation (AN) AdminQ command with a new
parameter allowing software to specify the Tx reference clock index to
be used during link restart.

This patch:
 - adds REFCLK field definitions to ice_aqc_restart_an
 - updates ice_aq_set_link_restart_an() to take a new refclk parameter
   and properly encode it into the command
 - keeps legacy behavior by passing REFCLK_NOCHANGE where appropriate

This prepares the driver for configurations requiring dynamic selection
of the Tx reference clock as part of the AN flow.
