Detailed Description
Link-on-use switch for the clockless half of unified parallel-IO engines (#4793).
The parallel-IO rule (agents/docs/cpp-standards.md -> "Parallel-IO Driver: Unified Clockless + SPI Engine") keeps one engine per peripheral for both modes. On ESP32 / ESP32-S3 that engine is also the default SPI bus, so an SPI-only sketch would otherwise link the whole clockless encode pipeline (wave8/wave3 transposers, clockless peripheral init) for code it can never run.
Every path that creates a clockless channel calls enableClocklessEncoders(). The engines reach their clockless pipeline only through state that this call installs, so a program that never creates a clockless channel never references that code and --gc-sections drops it. The engine and its Bus slot stay unified.
