gdb: remove move constructor and move assignment operator from cooked_index
Building with clang++-14, I see:
CXX dwarf2/cooked-index.o

We explicitly make cooked_index have a default move constructor and
move assignment operator. But it doesn't actually happen because
cooked_index has a field of type auto_obstack, which isn't movable.
We don't actually need cooked_index to be movable at the moment, so
remove those lines.
