Refactor unary operation constant folding code

This change splits TIntermConstantUnion::foldUnary into two functions: - foldUnaryWithDifferentReturnType: - Handles constant folding of operations where the return type has a different number of components compared to the operand type. - foldUnaryWithSameReturnType: - Handles constant folding of unary operations where the return type is the same as operand type.
