  [DirectX] Allow vector Allocas to be transformed into arrays (#145972)

fixes #145782

This change modifies `isArrayOfVectors` into `isVectorOrArrayOfVectors`.
The previous implementation did not support vector to array
transformations. Further it was too simplistic and didn't assume allocas
would create multidimensional arrays.
