net: wwan: Fix WWAN config symbols

Browse source 
There is not strong reason to have both WWAN and WWAN_CORE symbols,
Let's build the WWAN core framework when WWAN is selected, in the
same way as for other subsystems.

This fixes issue with mhi_net selecting WWAN_CORE without WWAN and
reported by kernel test robot:

Kconfig warnings: (for reference only)
   WARNING: unmet direct dependencies detected for WWAN_CORE
   Depends on NETDEVICES && WWAN
   Selected by
   - MHI_NET && NETDEVICES && NET_CORE && MHI_BUS

Fixes: 9a44c1cc63 ("net: Add a WWAN subsystem")
