Rename in_function_epilogue_p to stack_frame_destroyed_p

We concluded that gdbarch_in_function_epilogue_p is misnamed, since it
returns true if the given PC is one instruction after the one that
destroyed the stack (which isn't necessarily inside an epilogue),
therefore it should be renamed to stack_frame_destroyed_p.

I also took the liberty of renaming the arch-specific implementations to
*_stack_frame_destroyed_p as well for consistency.

gdb:
