This CL modifies the canonical interface for reusable executions: - Add new interface: IExecution with compute and computeFenced methods - Add new method IPreparedModel::createExecution In NNAPI runtime, the new interface IExecution is used to memoize request-specific execution resources (e.g. converted HAL request). The expected usage is that, IPreparedModel::createExecution will be invoked in the first computation of a reusable NDK ANNExecution object, and IExecution::compute* will be invoked repeatedly. The IPreparedModel::execute* methods are preserved to avoid redundant object creation and memoization overhead for a single-time (non-reusable) execution. For a vendor implementing the canonical interfaces, only the IPreparedModel::execute* methods will be called because there is currently no reusable execution at HAL interface. A DefaultExecution implementation is provided to reduce the work needed on the vendor side.
