[WASM] Prevent casting `undef` to `CosntantSDNode`
WebAssembly tries to cast an `undef` to `CosntantSDNode` during `LowerAccessVectorElement`.
These operations will trigger an assertion error in cast.
To avoid this issue, we prevent casting, and abort the lowering operation.
A unit test is also included.
