Pratik Dey 7b1c063848 feat(python): add type-safe expression builder API (#3150) ...

Introduces col(), lit(), func(), and Expr class as alternatives to raw
SQL strings in .where() and .select(). Expressions are backed by
DataFusion's Expr AST and serialized to SQL for remote table compat.

Resolves: 
- https://github.com/lancedb/lancedb/issues/3044 (python api's)
- https://github.com/lancedb/lancedb/issues/3043 (support for filter)
- https://github.com/lancedb/lancedb/issues/3045 (support for
projection)
