mesh: Allow group management cipher to be configured

This allows BIP-GMAC-128, BIP-GMAC-256, or BIP-CMAC-256 to be used
instead of the previously hardcoded AES-128-CMAC as the group management
cipher when using mesh with PMF. For now, this can be configured by
setting a single group_mgmt value in the network block and doing that
consistently through all the STAs in the mesh.
