gdb: Introduce new language field la_is_string_type_p
This commit is preparation work for the next commit, and by itself
makes no user visible change to GDB. I've split this work into a
separate commit in order to make code review easier.
This commit adds a new field 'la_is_string_type_p' to the language
struct, this predicate will return true if a type is a string type for
the given language.
Some languages already have a "is this a string" predicate that I was
able to reuse, while for other languages I've had to add a new
predicate. In this case I took inspiration from the value printing
code for that language - what different conditions would result in
printing something as a string.
A default "is this a string" method has also been added that looks for
TYPE_CODE_STRING, this is the fallback I've used for a couple of
languages.
In this commit I add the new field and initialise it for each
language, however at this stage the new field is never used.
