xfrm: make xfrm modes builtin
after previous changes, xfrm_mode contains no function pointers anymore
and all modules defining such struct contain no code except an init/exit
functions to register the xfrm_mode struct with the xfrm core.
Just place the xfrm modes core and remove the modules,
the run-time xfrm_mode register/unregister functionality is removed.

The xfrm*_mode_{transport,tunnel,beet} modules are gone.
v2: replace CONFIG_INET6_XFRM_MODE_* IS_ENABLED guards with CONFIG_IPV6
ones rather than removing them.
