libiberty: remove FINAL and OVERRIDE from ansidecl.h

libiberty's ansidecl.h provides macros FINAL and OVERRIDE to allow
virtual functions to be labelled with the C++11 "final" and "override"
specifiers, but with empty implementations on pre-C++11 C++ compilers.

We've used the macros in many places in GCC, but as of as of GCC 11
onwards GCC has required a C++11 compiler, such as GCC 4.8 or later.
On the assumption that any such compiler correctly implements "final"
and "override", I've simplified GCC's codebase by replacing all uses of
the FINAL and OVERRIDE macros in GCC's source tree with the lower-case
specifiers (via commits r13-690-gff171cb13df671 and
r13-716-g8473ef7be60443)

The macros are reportedly not used anywhere in binutils-gdb.

This patch completes this transition for GCC by eliminating the macros
from ansidecl.h.
