[QNN EP] Support Resize with 'asymmetric' transformation mode on HTP backend (#16060)
### Description
- Adds support for Resize with the `asymmetric` coordinate
transformation mode on the QNN HTP backend.
- Adds unit test that shows this is only correct if the `nearest_mode`
is `"floor"`.
### Motivation and Context
This is needed to enable more models to run on the QNN HTP backend.
Note:
QNN's ONNX converter tool translates an ONNX Resize op with `{mode:
"nearest", coordinate_transformation_mode: "asymmetric", "nearest_mode":
<ANYTHING>}` to QNN's ResizeNearestNeighbor with `{align_corners: 0,
half_pixel: 0}`.
Unit tests show that this is only accurate if the ONNX attribute
nearest_mode is "floor". Need to investigate how to handle other
rounding modes. Ideally, we would use QNN's own Resize operator (instead
of ResizeNearestNeighbor), but that doesn't support the "asymmetric"
coordinate transformation mode on the HTP backend.
