  [WebAssembly] Fix crash when selecting 64 bit lane extract operand

The tablegen patterns on vector_extract only match i32 constants, but
on wasm64 these come in as i64 constants. In certain situations this
would cause crashes whenever it couldn't select an extract_vector_elt
instruction.
Rather than add duplicate patterns for every instruction, this just
canonicalizes the constant to be i32 when lowering.
