inference: add face landmark detection support for Mediavision
Add face landmark detection support for Mediavision backend.
With this patch, move '_rects' member to each specific result structure,
and add _points to FldResultType for face landmark detection.

inference: apply abstract factory pattern
Apply abstract factory pattern. This patch uses abstract factory pattern
to create targeted inference service such as face detection, object detection
and so on from backend specific factory.
Regarding this, self-registeraion factory pattern is used to register
each inference service backend factory such as mediavision or mediapipe in
build time, and abstract factory pattern is used to create targeted inference
service from the inference service backend factory like below.
// create a given inference backend factory.
_factory = InferenceServiceFactory::instance().create("MvInferenceServiceFactory");
Ps. MvInferenceServiceFactory is inference service backend factory for Mediavision.
So other backend factory such as Mediapipe will be added later.
// create a target inference task service from the given inference backend factory
_infernce_service = _factory->createFaceDetection();
or
_infernce_service = _factory->createObjectDetection();

Apply self-registeration factory pattern to inference service.

will be registered to inference factory table in build time, and
it will create InferenceServiceDefault or InferenceServiceExternal class

modifies existing build script so that inference service directory
can be built-in.
This patch is just a previous step for applying abstract factory pattern
as we discussed.

input/camera_api: add sync API support
Add sync API support by implementing capture method of CameraApiBackend class.
According to Camera-api document below,
https://docs.tizen.org/application/native/api/mobile/4.0/group__CAPI__MEDIA__CAMERA__MODULE.html
For capture, this patch follows the Camera API state diagram. However,
one tricky way is needed to make sure to wait for the "Captured" state
because completed callback since camera_start_capture call will be called
by main thread so sync API of singleo framework cannot use the callback.
Therefore, to make sure to wait for the state, we use a tricky way by
checking if current state is "Captured".

add async manager for async API support
Add async manager class for async API supprort.
Async manager is used to support async API support for each service API.
Behavior summary to async manager:
There are two queues which are performed in each thread context.
One is incoming queue which manages input data feeded from input device
such as camera, screen capture module, and other external modules
through input service framework. Simply saying, input service framework
will push input data feeded from input device.
And other is outgoing queue which manages output data after the completion
of invoke such as inference. Regarding outgoing queue, a thread context
is created by async manager, and this thead context pops input data
from incoming queue, request an invoke with the input data and then
push the result to outgoing queue.
As such, one thread puts input data obtained from an input device into
an incoming queue, and the other thread retrieves input data from
the incoming queue, performs invoke, and puts the result of the execution
into an outgoing queue in parallel to utilize HW resource in maximum.

- services/auto_zoom directory

. A unique object corresponding to user-desired service.
. abstracted AI service
. actual implementation to user-desired AI service using various
generic services such as inference, training and remote computing
services.
. abstracted preprocess classes
. preprocessing class for convert user-given input or internally-feeded
input data to common data object which can be used for service
perform framework internally.
. abstracted input data types
. Common data type for contarining various types of data given by user
or internally-feeded such as camera, screen capture, image file
and so on.
- log directory
. message logging class which provides standard output in default and dlog
for Tizen as a Tizen backend.
- input directory
. abstracted input service classes which provide input feeded data through
Camera and screen capture module in platform independent manner.
Platform dependent camera or screen capture modules can be used as plugin
module. In default, OpenCV based camera backend is used, which is a built
in backend.
- inference directory
. abstracted inference service classes which provides platform independent
inference service.
. inference/backends directory
. Inference engine backend for the use of Mediavision framework.
In default, mediavision backend is used but possible to use external
framework through a plugin module.
