* Strictly enforce: trampoline must inherit from trampoline_self_life_support when used in combination with smart_holder
* Simplify test_class_sh_trampoline_basic.cpp,py (only one Abase is needed now)
* Replace obsolete sophisticated `throw value_error()` with a simple `assert()`
* Strictly enforce: trampoline should inherit from trampoline_self_life_support only if used in combination with smart_holder
* Resolve clang-tidy error

/__w/pybind11/pybind11/tests/test_class_sh_trampoline_basic.cpp:35:46: error: the parameter 'obj' is copied for each invocation but only used as a const reference; consider making it a const reference [performance-unnecessary-value-param,-warnings-as-errors]

* Disable new static_assert if PYBIND11_RUN_TESTING_WITH_SMART_HOLDER_AS_DEFAULT_BUT_NEVER_USE_IN_PRODUCTION_PLEASE is defined.
