Switch vector dimension handling to fixed-width `uint32_t` type,
update parsing/validation, and add boundary tests.
The dimension is parsed as `unsigned long` at first which is guaranteed
to be **at least** 32-bit long, which is safe to downcast to `uint32_t`.
Move `MAX_VECTOR_DIMENSION` from `cql3_type::raw_vector` to `cql3_type`
to ensure public visibility for checks outside the class.
Add tests to verify the type boundaries.
