Massage the `symbols` helpers to fill out {match all, match any} x
{substring match, exact match}:
| | Substring match | Exact match |
|-----------|----------------------------------------|-------------------------------|
| Match any | `object_contains_any_symbol_substring` | `object_contains_any_symbol` |
| Match all | `object_contains_all_symbol_substring` | `object_contains_all_symbols` |
As part of this, rename `any_symbol_contains` to
`object_contains_any_symbol_substring` for accuracy.
