cmake: rename linker_final_pass.cmd to linker.cmd

Browse source 
Since linker_final_pass.cmd is the actual linker script being
used to link the final Zephyr binary, rename it to linker.cmd.

This also renames LINKER_PASS2 to LINKER_ZEPHYR_FINAL simply
to clarify what it is used for, instead of ambiguous pass #n.
