esb: align to mpsl_fem_tx_power_split with phy

In the MPSL the `mpsl_fem_tx_power_split` function will change soon.
It will have the `phy` parameter. To smoothly transition through the
change in public API for FEM the new MPSL version will define a macro
`_MPSL_FEM_TX_POWER_SPLIT_HAS_PHY`.

This commit aligns the ESB to the new MPSL API.
For short transitional period both APIs are supprted.
