[WebAssembly][FastISel] Fold AND mask operations into ZExt load (#183743) 
FastISel emits separate load and AND instructions for bitmasking.
(before) %1:i32 = LOAD_I32 %addr; %2:i32 = AND_I32 %1, 255

Fold AND masks into ZExt loads by verifying operands with
maskTrailingOnes. A getFoldedLoadOpcode wrapper is implemented
to manage dispatching logic for better extensibility.
(after) %1:i32 = LOAD8_U_I32 %addr

Fixed: https://github.com/llvm/llvm-project/issues/180783
