[CALCITE-4795] In class SqlBasicCall, make the "operands" field private (part 1)

In class SqlBasicCall, the operands field is currently a
public array. This gives too much freedom for clients to do
crazy things, and creates unexpected behavior because the
array is not copied when a SqlBasicCall is cloned. We would
like to make the first private, but that would be a breaking
change, so we must do it over two releases.

This is part 1: deprecate the "operands" field; after 1.28,
part 2 will make the "operands" field private, and also
change it from an array to an immutable List. You will still
be able to call SqlCall.setOperand, but the whole new List
will be created.
