webnn: emulate rank-5 pow's input tensors in TFLite backend

This CL emulates rank-5 pow inputs in TFLite backend. TFLite's native
POW kernel only supports broadcasting up to rank 4. Extract the
rank-reduction logic (collapse broadcast shapes, else broadcast+flatten)
into a shared helper reused by logical binary ops, bump pow's supported
rank to 5, and add conformance tests.
