New field la_varobj_ops in struct language_defn

This is a follow-up series to move language stuff out of varobj.c.

This patch adds a new field la_varobj_ops in struct language_defn so
that each language has varobj-related options.  Not every language
supports varobj, and the operations are identical to operations of c
languages.

'struct language_defn' is the ideal place to save all language-related
operations.  After this patch, some cleanups can be done in patch 2/2,
which removes language-related stuff completely from varobj.c.

Regression tested on x86_64-linux.
