libstdc++: Define memory resource key functions non-inline (PR93208)
This prevents the vtables and RTTI from being emitted in every object
file that uses memory_resource and monotonic_buffer_resource.
Objects compiled by GCC 9.1 or 9.2 will contain inline definitions of
the destructors, vtable and RTTI, but this is harmless. The inline
definitions have identical effects to the ones that are now defined in
libstdc++.so so it doesn't matter if the inline ones are used instead of
calling the symbols exported from the runtime library.
PR libstdc++/93208
* config/abi/pre/gnu.ver: Add new exports.
* include/std/memory_resource (memory_resource::~memory_resource()):
Do not define inline.
(monotonic_buffer_resource::~monotonic_buffer_resource()): Likewise.
* src/c++17/memory_resource.cc (memory_resource::~memory_resource()):
Define.
(monotonic_buffer_resource::~monotonic_buffer_resource()): Define.
* testsuite/20_util/monotonic_buffer_resource/93208.cc: New test.
