Drishti Tripathi b368f2cc55 PR #2057: doc: clarify moved-from state for hash containers ...

Imported from GitHub PR https://github.com/abseil/abseil-cpp/pull/2057

Adds documentation to flat_hash_map, flat_hash_set, node_hash_map, and
node_hash_set clarifying the moved-from contract for Swiss table containers.

After a move, only destruction, assignment, and clear() are guaranteed
safe. Any other operation (e.g. size(), empty(), iteration) results in
undefined behavior.

Fixes #1928
Merge 64990acd7a into c7269872a5

Merging this change closes #2057
