Type byte-address inputs of the two-stage RLE lookup helpers

Each independently inspected helper captures two integer arguments as byte lookup-table addresses and computes table1[table2[sourceByte]]. Table numbers follow their exact unchanged upstream API identities, not execution order. The clipped helper additionally uses incoming EDX as its byte-output address. Correct all five integer address representations and generic names coherently; preserve existing byte-buffer/scalar inputs, chosen names, void results, fastcall arity/storage and RET16/RET28. Table inputs are captured in EDI/ESI before reused stack locations become scratch. No sibling inference or allocation extent assumed.
