  -----------
  [DebugInfo] Emit DW_AT_const_value for constexpr array static members (#182442)

Clang does not emit a `DW_AT_const_value` in DWARF, while GCC does. This
patch fixes this issue through handling Array `APValues` and respective
handling in the backend through `ConstantDataSequential`

Fixes #165220
