Fix DML Resize ROI axis expansion (#32747)
This pull request improves the handling and validation of the `roi`
(region of interest) input in the Resize operator, and adds
corresponding tests to ensure correct behavior. The main focus is on
ensuring the `roi` input length matches expectations and correcting how
ROI values are mapped, particularly when axes are specified.
**Operator logic improvements:**
* Added validation to ensure that the `roi` input length is exactly
twice the number of axes, preventing misconfiguration and potential
runtime errors.
* Corrected the indexing logic for mapping ROI values to the default ROI
vector, ensuring correct placement of values when axes are specified.
* Updated the internal representation of `m_regionOfInterest` to use the
processed ROI values.
**Test coverage enhancements:**
* Added a new unit test `Axes_Roi_18` to verify correct Resize operator
behavior when both `axes` and `roi` are specified, including correct
output for a simple input.
* Adjusted the `Roi_TooShortForAxes_18` test to remove the DML execution
provider from the expected failure list, reflecting updated provider
support or behavior.
