    Two-Winding Transformer?

    We only need a unipolar positive DC voltage.
    Can the IRA2153SD work with a simple two-winding transformer and a full-bridge rectifier?
    What are the drawbacks?
    Is there a different Infineon device that would work better in this configuration, such as a full-bridge gate-driver?

    The IRS2453D is a full bridge gate driver based on the IR2153D self-oscillating half-bridge gate driver IC.

    can the half-bridge driver work without a center-tap, by using appropriate rectifier?

    Yes. The IC biasing conditions including the VCC should be met with the rectifier. See below application notes:
