Change dynamic fusion API to return destination tensor info

The new dynamic fusion API is introduced in the following patch:
https://review.mlplatform.org/c/ml/ComputeLibrary/+/8906

For each operator (except Conv2D, which is migrated in the above patch), we
   - remove destination tensor from is_supported, validate and create calls
   - make create_op return ITensorInfo* to the intermediate destination object

Affected operators:
   - DepthwiseConv2D
   - Cast
   - Elementwise Ops
   - Clamp
   - Reshape
   - Resize
