  [MLIR][LLVM] Avoid creating invalid DICompositeTypes in import (#70797)

This commit ensures that the debug info import skips `DICompositeTypes`
that have an array type tag and failed to translate the base type. This
is necessary because array `DICompositeTypes` require a base type to be
valid.
Note that this is currently not verified in LLVM, instead it leads to an
explosion of the `ASMPrinter`.
