Missing windows support for building from source

[MordechaiHadad]

#38 currently lacks support for windows.

[MordechaiHadad]

It seems for now that the commands that are required to be ran in order to build neovim from source on windows are:
(MSVC only)

mkdir .deps
cd .deps
cmake ../cmake.deps
cmake --build .

cd ..
mkdir build
cd build
cmake ..
cmake --build .

but compared to building on linux it is much longer, main reason I believe is not having libuv installed.

currently only builds successfully when using Developer PowerShell for VS 2022

You could in theory use Import-VisualStudioVars from this https://github.com/Pscx/Pscx but

1. I dunno how to do that, instructions unclear
2. This still limits you to being stuck with one shell(powershell)

[MordechaiHadad]

I'll probably just add the commands above and specify that it will require using VS Developer shell for now... and try to come up with a better solution in a later patch

This issue is basically done but one con is needing to use the VS Developer shells now
