DML EP add a registration for Shape and Size (#13442)

### Description
Add a DML registration for Shape to avoid copying back to the CPU just
to get the shape of a GPU tensor.



### Motivation and Context
When using free dimensions, many Transformers models extensively use the
`Shape` operator. This causes hundreds of GPU->CPU copy that should be
completely avoidable. Note that this change also uses the same
heuristics as other providers (e.g. CUDA) to force some tensors on the
CPU in certain situations.
