feat: 切换后端至PaddleOCR-NCNN，切换工程为CMake

Browse Source 
1.项目后端整体迁移至PaddleOCR-NCNN算法，已通过基本的兼容性测试
2.工程改为使用CMake组织，后续为了更好地兼容第三方库，不再提供QMake工程
3.重整权利声明文件，重整代码工程，确保最小化侵权风险

Log: 切换后端至PaddleOCR-NCNN，切换工程为CMake

// Clear(FN fn) takes a functor object that releases the objects, if they need cleanup.

// {

/*
This header file defines an object to help queue and serialize
asynchronous operations.
Background:
To perform an operation asynchronously in Media Foundation, an object
does one of the following:
1. Calls MFPutWorkItem(Ex), using either a standard work queue
identifier or a caller-allocated work queue. The work-queue
thread invokes the object's callback.
2. Creates an async result object (IMFAsyncResult) and calls
MFInvokeCallback to invoke the object's callback.
Ultimately, either of these cause the object's callback to be invoked
from a work-queue thread. The object can then complete the operation
inside the callback.
However, the Media Foundation platform may dispatch async callbacks in
parallel on several threads. Putting an item on a work queue does NOT
guarantee that one operation will complete before the next one starts,
or even that work items will be dispatched in the same order they were
called.
To serialize async operations that should not overlap, an object should
use a queue. While one operation is pending, subsequent operations are
put on the queue, and only dispatched after the previous operation is
complete.
The granularity of a single "operation" depends on the requirements of
that particular object. A single operation might involve several
asynchronous calls before the object dispatches the next operation on
the queue.
*/
//-------------------------------------------------------------------
// OpQueue class template
//
// Base class for an async operation queue.
//
// TOperation: The class used to describe operations. This class must
// implement IUnknown.
//
// The OpQueue class is an abstract class. The derived class must
// implement the following pure-virtual methods:
//
// - IUnknown methods (AddRef, Release, QI)
//
// - DispatchOperation:
//
// Performs the asynchronous operation specified by pOp.
//
// At the end of each operation, the derived class must call
// ProcessQueue to process the next operation in the queue.
//
// NOTE: An operation is not required to complete inside the
// DispatchOperation method. A single operation might consist
// of several asynchronous method calls.
//
// - ValidateOperation:
//
// Checks whether the object can perform the operation specified
// by pOp at this time.
//
// If the object cannot perform the operation now (e.g., because
// another operation is still in progress) the method should
// return MF_E_NOTACCEPTING.
