  [CIR] Fix incorrect ConstArrayAttr trailing_zeros parsing (#188742)

Closes #187699 .

Fix incorrect parsing of `ConstArrayAttr`. `parse` method incorrectly
used type of `elts` parameter as type of the whole array. This means
that when reading back text or bytecode clangir files attribute did not
have correct type and correct `trailingZerosNum`. Type was always of
inner `elts`, meaning smaller then actual type if any trailing zeros
were present and `trailingZerosNum` was always zero.
