net/mlx5e: Prevent WQE metadata conflicts between timestamping and offloads

Update the WQE metadata assignment to avoid overriding existing
metadata when setting the sysport timestamp ID. Since timestamp IDs are
limited to 256 values, they use only the lower 8 bits of the metadata
field.

To avoid conflicts, move IPsec and MACsec metadata ID to bits 8 and 9,
and shift the MACsec fs_id accordingly. This ensures safe coexistence
of timestamping and offload features that use the same metadata field.
