IVGCVSW-7830 Add backend optimizations to remove Reshapes where possible

 * Added optimization to remove reshapes for Neon and Ref Backends
   by using overridden TensorInfos
 * Added ability to delete Subgraphs during Optimization
 * Fixed naming error in NeonEndToEndTests and CLEndToEndTests
 * Added LayerNameAndTypeCheck for testing.
 * Fixed error where layers were not marked as altered when removed in
   CLBackend
