[WebAssembly][FastISel] Emit signed loads for sext of i8/i16/i32 (#182767) 
FastISel currently defaults to unsigned loads for i8/i16/i32 types,
leaving any sign-extension to be handled by a separate instruction. This
patch optimizes this by folding the SExtInst into the LoadInst, directly
emitting a signed load (e.g., i32.load8_s).

When a load has a single SExtInst use, selectLoad emits a signed load
and safely removes the redundantly emitted SExtInst.

Fixed: #180783
