[DAG] computeKnownFPClass - add ISD::EXTRACT_VECTOR_ELT handling (#190307) This PR implements `ISD::EXTRACT_VECTOR_ELT` in `SelectionDAG::computeKnownFPClass` to propagate floating-point class information from vector sources to extracted scalar elements. Additionally, added RISC-V test coverage for `ISD::EXTRACT_VECTOR_ELT`. Fixes #189585
