[SPIR-V]: Fix creation of constants of array types in SPIRV Backend (#96514)

This PR fixes https://github.com/llvm/llvm-project/issues/96513.

The way of creation of array type constant was incorrect: instead of
creating [1, 1, 1] or [1, 1, 1, 1, 1, ....] constants, the same [1]
constant was always created, substituting original composite constants.
This in its turn led to a situation when only one of constants might
exist in the code without emitting invalid code, the second constant
would be eventually rewritten to the first constant, because a key to
address both was an array of a single element (like [1]).

This PR fixes the issue and purges from the code unneeded copy/pasted
clone of the function that creates an array constant.
