[Feature] Resize varshape to constant sized Tensor path

[zacharyvincze]

Add variable-shape Resize

Summary

Adds a Resize overload that resizes an ImageBatchVarShape (batch of differently-sized images) into a uniform NHWC output tensor, each image scaled independently. Builds on the varshape image-batch and wrapper infrastructure from the base branch.

Changes

• op_resize (.hpp / .cpp) — new operator()(stream, ImageBatchVarShape& in, Tensor& out, interp, device). The uniform and varshape paths share a single dispatch_resize_launch; input is non-const because exportData() advances the batch's lazy device-sync state. Validates device, uniform format, dtype [U8, F32], and channels [1,3,4].
• Resize kernels (device / host) — drop the host-precomputed scaleX/scaleY params; scale is now derived per-batch-index from input.width(batch)/output.width(). For a TensorWrapper this is constant across the batch (identical to before); for an ImageBatchVarShapeWrapper it yields each image's own scale.
• Validation helpers — new CHECK_IMAGE_BATCH_* macros (device, not-empty, uniform-format, datatypes, channels) mirroring the existing CHECK_TENSOR_* set.
• Sample — resize_var_shape.cpp demonstrates varshape resize; wired into samples CMake/README.
• Tests — golden-model coverage for the varshape path in test_op_resize.cpp.

Notes

• Depends on [Feature] Add kernel-accessible ImageBatchVarShapeWrapper #154

Pull request overview

Adds a variable-shape Resize path that takes an ImageBatchVarShape (heterogeneous input sizes) and produces a uniform NHWC Tensor, while also refactoring the wrapper stack (border/interpolation) to work generically over both uniform (TensorWrapper) and varshape (ImageBatchVarShapeWrapper) inputs. This PR also introduces new core Image / ImageData / ImageBatch*Data types, a varshape descriptor-table implementation, and expands samples/tests accordingly.

Changes:

• Add Resize::operator()(stream, ImageBatchVarShape&, Tensor&, interp, device) and unify uniform+varshape dispatch via a shared launch helper; resize scale is now derived per-batch-index inside kernels.
• Introduce Image, ImageBatchVarShape, ImageData*, ImageBatch*Data (and varshape descriptor table) to support varshape batching and exported descriptor snapshots.
• Update many operators/tests to use TensorWrapper + MakeBorderWrapper/MakeInterpolationWrapper, and add a new varshape resize sample + expanded test coverage.
