feat: add helper macro and new Win32 function.

- add IsValidCodePage in WinFctHelper to check whether code page number is valid.
- add 6 macros to batchly (add / set default) (move / copy) (constructor / assign operator).
- add default or delete (copy / move) (constructor / assign operator) for some classes.

/**
\page library_macros Library Macros
In this page we will introduce the macros defined by this library
which can not be grouped in other topic.
\section library_macros__platform_checker Platform Checker
In many cross platform applications,
programmer usually write code adapted to different platforms in one source file
and enable them respectively by macros representing the target platform.
As a cross platform library,
YYCC also has this feature and you can utilize it if you don't have other ways to so the same things.
\subsection library_macros__platform_checker__values Values
YYCC always define a macro called \c YYCC_OS to indicate the system of target platform.
In implementation, it will check following list from top to bottom to set matched value for it.
\li \c YYCC_OS_WINDOWS: Windows environment. It is done by checking whether environment define \c _WIN32 macro.
\li \c YYCC_OS_LINUX: In current implementation, this means target platform is \b NOT Windows.
\subsection library_macros__platform_checker__usage Usage
Now you know any possible value of \c YYCC_OS.
The next step is how to use it to enable specified code in specific target platform.
We take Windows platform for example.
Assume \c blabla() function is Windows specific.
We have following example code:
\code
#if YYCC_OS == YYCC_OS_WINDOWS
blabla();
#endif
\endcode
It's enough and simple that use \c \#if to bracket the Windows specified code.
\section library_macros__batch_class_copy_move Batch Class Copy / Move Functions
YYCC provides 6 macros to batchly remove class copy constructor and move constructor,
or set default class copy constructor and move constructor.
<UL>
<LI>
\c YYCC_DEL_CLS_COPY: Declare following 2 statements which delete copy constrcutor and copy assign operator.
<UL>
<LI><TT>CLSNAME(const CLSNAME&) = delete;</TT></LI>
<LI><TT>CLSNAME& operator=(const CLSNAME&) = delete;</TT></LI>
</UL>
</LI>
<LI>
\c YYCC_DEL_CLS_MOVE: Declare following 2 statements which delete move constrcutor and move assign operator.
<UL>
<LI><TT>CLSNAME(CLSNAME&&) = delete;</TT></LI>
<LI><TT>CLSNAME& operator=(CLSNAME&&) = delete;</TT></LI>
</UL>
</LI>
<LI>\c YYCC_DEL_CLS_COPY_MOVE: The combination of \c YYCC_DEL_CLS_COPY and \c YYCC_DEL_CLS_MOVE.</LI>
<LI>
\c YYCC_DEF_CLS_COPY: Declare following 2 statements which set default copy constrcutor and copy assign operator.
<UL>
<LI><TT>CLSNAME(const CLSNAME&) = default;</TT></LI>
<LI><TT>CLSNAME& operator=(const CLSNAME&) = default;</TT></LI>
</UL>
</LI>
<LI>
\c YYCC_DEF_CLS_MOVE: Declare following 2 statements which set default move constrcutor and move assign operator.
<UL>
<LI><TT>CLSNAME(CLSNAME&&) = default;</TT></LI>
<LI><TT>CLSNAME& operator=(CLSNAME&&) = default;</TT></LI>
</UL>
</LI>
<LI>\c YYCC_DEF_CLS_COPY_MOVE: The combination of \c YYCC_DEF_CLS_COPY and \c YYCC_DEF_CLS_MOVE.</LI>
