CoreML: ML Program DepthToSpace #21426

Description

Add DepthToSpace ML Program support.

We need to manually handle CRD format by decomposing the steps.
Luckily we can work around CoreML's 5D limit as the data movement is not affected by merging the batch dimension with the channel dimension.

Motivation and Context

Improve CoreML coverage for high priority models.

- Add Concat (#21423)
- Add DepthToSpace (#21426)
- Add LeakyRelu (#21453)
- Add test scripts (#21427)
- Add ability to set coreml flags from python (#21434)

Also updated partitioning utils to support dropping constant initializers from a ComputeCapability's inputs. We copy these to a CoreML model so don't need the originals. If they remain as inputs ORT can't free them as they appear to be in use.

Misc changes
- Fix SkipLayerNormFusion incorrectly setting `modified`
  - causes unnecessary loops of the L2 transformers
