feat: windows support

[jinzhongjia]

This PR is used to add windows support, but do not merge it yet.
The PR still needs more testing

I noticed that page_allocator is used extensively in the overall code. This memory allocator will directly allocate the entire page, and its speed is slower.

Now I created a new file called tool.zig, which stores an allocator. Maybe we can use gpa(GeneralPurposeAllocator)

[jinzhongjia]

And I adjusted the build mode in build.zig to default, which will speed up compilation on windows and facilitate debugging.

[jinzhongjia]

I also found that the use of std.debug.print seems a bit excessive. Zig officially recommends using std.log to achieve this

[jinzhongjia]

and tested the following latest released zvm under my wsl2, it seems to have some issues

[jinzhongjia]

But it seems that they are all executed successfully, and further investigation may be needed.

[jinzhongjia]

Oh, I see that most of the situations above have been mentioned by you in other issues

Yeah, if there is something not yet covered feel free to open up an issue.

For not getting this PR too big. You can open up a pull request for these improvements or like i mentioned open up an issue.

IIRC github action runner are using "windows-server" which it is not the same as enterprise windows. Had some trouble because of that in other projects. For the first integration that could be fine, but maybe using something like this https://hub.docker.com/_/microsoft-windows-base-os-images could be better.

Overall looking great, really appreciate your contribution. Ping me if you think it should be reviewed.

[jinzhongjia]

Then if you think there is no problem, I have done some tests and it seems that we can temporarily merge the PR.

[jinzhongjia]

Regarding other issues, I will open a new PR separately.

[hendriknielaender]

Looks good to me! Great work.

[jinzhongjia]

The current code can only be said to work, after the PR is merged, I will reorganize the code logic, including fixes for issues that have been raised

[jinzhongjia]

Later we can try to apply for administrator rights when needed. The speed of copying files on the Windows platform is really not ideal.
