gdb: Convert language_data::la_exp_desc to a method

Browse source 
Convert language_data::la_exp_desc member variable to a virtual
method language_defn::expression_ops.  The change of names brings this
method more into line with the existing varobj_ops method, that also
returns a table of function pointers.

There should be no user visible changes after this commit.
