[smart_holder] Introduce PYBIND11_SMART_HOLDER_DISABLE option. (#5348)
* Step 1: Establish new `PYBIND11_SMART_HOLDER_ENABLED` macro, but only under include/pybind11/

At the stage `PYBIND11_HAS_INTERNALS_WITH_SMART_HOLDER_SUPPORT` and `PYBIND11_SMART_HOLDER_ENABLED` are still equivalent.

* Systematically replace all `PYBIND11_HAS_INTERNALS_WITH_SMART_HOLDER_SUPPORT` with `PYBIND11_SMART_HOLDER_ENABLED` under tests/ and ubench/

As at the previous stage, `PYBIND11_HAS_INTERNALS_WITH_SMART_HOLDER_SUPPORT` and `PYBIND11_SMART_HOLDER_ENABLED` are still equivalent.

* Introduce `PYBIND11_SMART_HOLDER_DISABLE` option.

* `#ifdef` out entire `wrap()` function to avoid `unused-parameter` warning-as-error under macos-13
