[API] Set Property API for Neural Network Layer

. Implement Set Property API for Neural Network Layer
  - Each layer has setProperty methods with its own Property enum
  class.
  - Layer Class has virtual setProperty Class
  - Seperate parseType and make parse_util.h & cpp to use other
  files.
  - Use TensorDim for Define demesion of hidden layer
