test: add opt-in test-parse-rv64-wide target for rv64 128-bit scalars

End-to-end coverage of __int128 (i128_*) and IEEE-754 binary128 long double
(ldbl128_*) built with cfree and run on riscv64 — exercises the soft-float / i128
runtime lowering, the LP64D register-pair ABI for 16-byte scalars, and the
conditional-branch range fix the large soft-float helpers depend on. Opt-in
(needs qemu/podman riscv64), excluded from the default test target like
test-smoke-rv64.
