inconsistent cmake version requirements

[yamt]

with #4076, we started using CMAKE_CURRENT_FUNCTION_LIST_DIR, which requires cmake 3.17.

on the other hand, many of our CMakeLists.txt have cmake_minimum_required with 3.14.

Which option do you prefer?

• Updating cmake_minimum_required() in all CMakeLists.txt to 3.17. (we can make it happen with Keep fix the CMake compatibility issue #4180)
• Or replacing CMAKE_CURRENT_FUNCTION_LIST_DIR with an alternative?

* Updating `cmake_minimum_required()` in all CMakeLists.txt to 3.17. (we can make it happen with [Keep fix the CMake compatibility issue #4180](https://github.com/bytecodealliance/wasm-micro-runtime/pull/4180))

* Or replacing `CMAKE_CURRENT_FUNCTION_LIST_DIR` with an alternative?

i prefer the latter if it can be done in a reasonable way.
