Windows ARM64 support

[driver1998]

Summary

• Only TSF and IME clients are ported to ARM, WeaselServer and other components are kept as x86.
• Supports x86/x64/ARM32/ARM64 apps.

Notes

Pass arm64 to build.bat to build ARM support, you'll need the following Visual Studio Components:

• C++ ARM build tools & MFC
• C++ ARM64 build tools & MFC
• C++ ARM64EC build tools (This is now merged into ARM64 build tools in latest VS 2022)

ARM64X redirecton DLLs are used for ARM64 to support x64 and ARM64 apps. weasel.dll and weasel.ime are wrappers that redirects to weaselARM64 or weaselx64 depending on the app calling them. And that's also why three files are needed in system32 now.

This is required since there is no WOW redirection in the case of x64 on ARM64 and they have to somehow share the same system32 directory.

Screenshots

Windows Search (ARM64)

Mail app (ARM32)
Note: ARM32 version will not be installed on systems without ARM32 app support (Windows 11 24H2 and higher).

QQ (x86)

mintty (x64)

Works on Windows 11 (build 22621.1265) on ARM64 (Dev Kit 2023)

@fxliang 的分支合并之后变了很多东西，有空我再rebase一下，最好是等 #886 合并之后。

另外 STL 那边的问题似乎是解决了，可以研究一下怎么将TSF Client编译成一个ARM64X DLL了，这样部署可以简化很多（能删掉WeaselSetup的一坨hacky代码）

我是没有测试条件，没有办法测试确认的，之前有看了下，修改也不算多，新增参数建议改成默认参数放到最后，这样非ARM的调用可以不用改，其余暂时未看细

noarm64 现在就是放最后的
不过跟x64一样现在也是默认开了编译，因为NSIS脚本写了ARM64的文件，不编译出来我怕打不了安装包

[driver1998]

Rebase 到最新 master，变化如下：

• boost 1.83 在 MSVC ARM64 下编译不过：Fix use of intrinsics on windows ARM platforms boostorg/json#928 ，1.84 没有问题。看到 librime 已经在用 1.84 了，这里顺带更新。
• STL 的问题解决之后单个 ARM64X DLL 确实能链接成功，但加载输入法时会崩（然后崩完之后能正常工作，狗头），先继续用重定向
• ARM64 支持改为默认不编译，build.bat arm64 开启
