Describe the enhancement requested

Conversion of a range of std::tuple objects can be converted into Arrow Tables. However, while Arrow supports several standard C++ data types for this conversion, it lacks direct support for fixed-size lists. At present, Arrow supports Lists via std::vector, but there is no implementation for fixed-size lists(std::array), which are often used in scenarios where size is predetermined for performance or structural reasons.

### What changes are included in this PR?
This PR introduces support for fixed-size lists in Apache Arrow's STL conversion.  Added specializations for arrow::stl::ConversionTraits<T> and arrow::CTypeTraits<T> to handle std::array as a fixed-size list and also Unit Test.

### Are these changes tested?
Yes, new type is tested.

### Are there any user-facing changes?
