IVGCVSW-7031 Generate static execute network

 * Build ExecNet lib dependencies as object libs except libarmnn
 * Disable PIPE when building static ExecNet
 * Remove multiple definition from AsyncExecutionCallback
 * Disable DynamicBackend for ExecNet Static build
 * Disable inference  tests for TfLiteParser and ONNX during static ExecNet
 * Remove Tensorflow Parser if condition
 * Add Disable thread macro to InferenceModel
 * Don't compile dynamic backend symbols in Runtime.cpp for Baremetal and
   Exenet Static
