Optimize ArrowBytesViewMap: fuse hash+insert, shrink entries, remove generic

[Dandandan]

Which issue does this PR close?

Performance optimization, no issue.

Rationale for this change

ArrowBytesViewMap is on the hot path for GROUP BY and COUNT DISTINCT on StringView/BinaryView columns. This PR applies three optimizations to improve cache efficiency and reduce memory overhead.

What changes are included in this PR?

1. Fuse hash computation with hash table probe: Instead of a two-pass approach (batch create_hashes then per-element probe), compute the hash and fetch non-inline bytes once per element. For non-inlined views (>12 bytes), the string data is kept cache-hot for the immediately-following equality comparison, avoiding a redundant pointer chase into the input array's data buffers.

2. Shrink hash table entries from 32 to 16 bytes: Entry<V> (u128 view + u64 hash + V payload) → (usize, u64) (index + hash). Views are looked up via the index into the existing views vec on demand. This means more entries fit per cache line during hash table probing.

3. Remove the V generic parameter: The only two usages were ArrowBytesViewMap<()> (set) and ArrowBytesViewMap<usize> (group-by), where the usize payload was always the insertion-order index — which is already implicit in the views vec position. The two-callback API (make_payload_fn + observe_payload_fn) is simplified to a single observe_fn(usize).

Are these changes tested?

Covered by existing tests (8 unit tests in binary_view_map + 26 group_values tests all pass).

Are there any user-facing changes?

No user-facing changes. ArrowBytesViewMap API is simplified but it is not part of the public API.
