genConsumeOperands(blkOp) routed the contained GT_INIT_VAL through genConsumeRegs and tripped its OperIsLeaf assert. Replace the call with explicit consume of dest and the unwrapped src, as other targets do. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Pull request overview
This PR updates WASM RyuJIT codegen for GT_STORE_BLK so that when the initblk fill value is wrapped in a contained GT_INIT_VAL, codegen consumes the wrapped value (gtGetOp1()) instead of routing the GT_INIT_VAL wrapper through genConsumeRegs (which asserts on non-leaf contained nodes in codegenlinear.cpp).
Changes:
- Replace
genConsumeOperands(blkOp)with explicit consumption ofdestand an unwrappedsrcwhensrcis a containedGT_INIT_VAL. - Add an assertion documenting the invariant that
GT_INIT_VALshould be contained in this path.
