[RyuJIT WASM] Add GT_NO_OP and GT_NOP handlers to genCodeForTreeNode (#122328) The WASM codegen was missing handlers for `GT_NO_OP` and `GT_NOP` node types in `CodeGen::genCodeForTreeNode`, causing failures when these nodes were encountered during code generation. ## Changes - **GT_NOP**: Added case that breaks immediately (marker-only node, emits no code) - **GT_NO_OP**: Added case that emits `INS_nop` instruction (non-deletable NOP) Implementation matches existing patterns across x86, ARM, and RISC-V architectures. ```cpp case GT_NOP: break; case GT_NO_OP: instGen(INS_nop); break; ```
