wifi: iwlwifi: mvm: Add helper functions to update EMLSR status

There are reasons for which we need to exit EMLSR, but not to block it
completely, and there are reasons for which we need to block EMLSR.

For both reason types we have the enum iwl_mvm_esr_state, when the
blocking reasons are stored in the `mvmvif::esr_disable_reason` bitmap.

This change introduces the APIs to use in the different cases:
- iwl_mvm_exit_esr - will exit from EMLSR mode.
- iwl_mvm_block_esr - will update the bitmap and exit EMLSR, to
  be used for the blocking reasons only.
- iwl_mvm_unblock_esr - will update the bitmap. To be used for the
  blocking reasons only.
