Remove dwarf2_per_cu_data::text_offset

This method simply returns the text offset of the objfile associated to
the dwarf2_per_cu_data object.  Since dwarf2_per_cu_data objects are
going to become objfile-independent, we can't keep this method.  This
patch removes it.

Existing callers need to figure out the in the context of which objfile
this is being used, and call text_offset on it.  Typically, this comes
from a symbol baton, where we store the corresponding
dwarf2_per_objfile.
