  [WebAssembly] getMemoryOpCost and getCastInstrCost (#122896)

Add inital implementations of these TTI methods for SIMD types. For
casts, The costing covers the free extensions provided by extmul_low as
well as extend_low. For memory operations we consider the use of
load32_zero and load64_zero, as well as full width v128 loads.
