#### AI description  (iteration 1)
#### PR Classification
New feature: Adds support for collation-aware hashing of arrays and documents in BSON.

#### PR Summary
This pull request introduces collation-aware hashing for BSON arrays and documents, enhancing the handling of collation in hash sets. It refactors existing hash functions to accommodate collation strings and recursive hashing of nested BSON structures.
- `hashset_utils.c`: Implements collation-aware hashing functions for BSON values, including recursive handling of arrays and documents.
- `bson_expression_set_operators.c`: Replaces existing hash set creation with collation-aware hash set creation.
- `bson_dollar_operators.c`: Updates logic to use collation-aware hash sets for `$in` queries, removing unsupported scenarios.
- `hashset_utils.h`: Adds a new struct `BsonValueHashEntry` to store BSON values with collation strings.
- `collation.h`: Moves `IsBsonTypeCollationAware` function to handle collation applicability checks.
