Return early from JIT lowering for compile-time zero-length MCOPY and lower compile-time zero-size EXTCODECOPY to an account-access-only runtime helper. Avoid emitting dynamic zero-length copy branches, memory expansion and copy-gas IR, runtime copy calls, and memory-size reloads for statically empty copy operations while preserving EIP-2929 account access charging for EXTCODECOPY.
