CoreML: Aggregated changes to add all required ops for priority model (#21472) ### Description <!-- Describe your changes. --> Add these changes to one PR to simplify checkin - Add Concat (#21423) - Add DepthToSpace (#21426) - Add LeakyRelu (#21453) - Add test scripts (#21427) - Add ability to set coreml flags from python (#21434) Other changes - updated partitioning utils to support dropping constant initializers from a ComputeCapability's inputs. - noticed that the list of inputs to the coreml model was unexpectedly long due to this - we copy constant initializers to a CoreML model so don't need the originals, and if they remain as inputs ORT can't free them as they appear to be in use. ### Motivation and Context <!-- - Why is this change required?
