gdb: move pascal_language into p-lang.h

Move the pascal_language class declaration into the p-lang.h header
file.  This allows for the function implementations to be spread over
the different p-*.c files without the need for global trampoline
functions.

As a consequence of this change many of the Pascal value and type
printing helper functions have become member functions within the
pascal_language class.

There should be no user visible changes after this commit.
