PR fortran/95826 - Buffer overflows with PDTs and long symbols

With PDTs (parameterized derived types), name mangling results in variably
long internal symbols.  Use a dynamic buffer instead of a fixed-size one.

gcc/fortran/
PR fortran/95826
* decl.c (gfc_match_decl_type_spec): Replace a fixed size
buffer by a pointer and reallocate if necessary.
