[clang-tidy] Add new check cppcoreguidelines-pro-bounds-array-to-pointer-decay

Summary:
This check flags all array to pointer decays.

Pointers should not be used as arrays. array_view is a bounds-checked,
safe alternative to using pointers to access arrays.

This rule is part of the "Bounds safety" profile of the C++ Core
Guidelines, see
https://github.com/isocpp/CppCoreGuidelines/blob/master/CppCoreGuidelines.md#-bounds3-no-array-to-pointer-decay
