  [CIR][NFC] Remove unused DataLayout in array lowering (#201408)

The per-element loop in CIRAttrToValue::visitCirAttr(ConstArrayAttr) constructed an mlir::DataLayout for every element of an ArrayAttr-backed constant array and never used it.  Constructing a DataLayout walks the parent ops to gather the layout spec, so for an N-element array this was N redundant constructions on the lowering path.  Removing the dead local is NFC -- the generated IR is unchanged.

Split out of #198427, where it was flagged as an unrelated drive-by.
