gdb: Convert language la_get_symbol_name_matcher field to a method

This commit changes the language_data::la_get_symbol_name_matcher
function pointer member variable into a member function of
language_defn.

There should be no user visible changes after this commit.

Before this commit access to the la_get_symbol_name_matcher function
pointer was through the get_symbol_name_matcher function, which looked
something like this (is pseudo-code):

  <return-type>
  get_symbol_name_matcher (language_defn *lang, <other args>)
  {
    if (current_language == ada)
      current_language->la_get_symbol_name_matcher (<other args>);
    else
      lang->la_get_symbol_name_matcher (<other args>);
  }

In this commit I moved the get_symbol_name_matcher as a non-virtual
function in the language_defn base class, I then add a new virtual
method that is only used from within get_symbol_name_matcher, this can
then be overridden by specific languages as needed.  So we now have:

  class language_defn
  {
    <return-type> get_symbol_name_matcher (<args>)
    {
      if (current_language == ada)
        return current_language->get_symbol_name_matcher_inner (<args>);
      else
        return this->get_symbol_name_matcher_inner (<args>);
    }

    virtual <return-type> get_symbol_name_matcher_inner (<args>)
    {
        ....
    }
  }
