msvc: include deps when linking

[gBillal]

In this PR we fix the issue of linking libraries declared in the deps config.

Also I deleted the instruction that deletes the whole folder before starting compilation because it deletes any compiled natives/libs before the current one (if they're in the same directory or on a sub-directory)

Pull request overview

This PR addresses a missing feature in the Visual Studio toolchain where dependencies declared in the deps configuration were not being linked during compilation. It also improves the directory handling to prevent deletion of previously compiled artifacts.

Changes:

• Added logic to extract and format dependency library paths for MSVC linking commands
• Modified directory setup from recursive deletion and recreation to conditional creation only
• Introduced helper functions paths/2 and path/1 to handle path formatting and quoting

Static libraries (.lib files created by the lib tool) are archives of object files and typically don't link other libraries. The lib command may not properly handle the deps parameter. In the Unix implementation (common/unix.ex, line 74-76), the ar command for :lib type natives intentionally does not include deps, as dependencies are resolved when the static library is later linked into an executable or shared library. Consider removing deps from this lib command to match the Unix behavior.

Suggested change

	~s[(lib /OUT:"#{PathHelper.fix_slashes(output_path)}.lib" *.obj #{deps})]
	~s[(lib /OUT:"#{PathHelper.fix_slashes(output_path)}.lib" *.obj)]

The path function uses Path.expand() and adds quotes but doesn't apply PathHelper.fix_slashes() to convert forward slashes to backslashes for Windows. This is inconsistent with how other paths are handled in this file (see lines 35, 39, 52, 72, 84) where PathHelper.fix_slashes() is used. The Unix implementation also uses Path.expand() in its path function, but that's appropriate for Unix systems. On Windows, the dependency paths may contain forward slashes that need to be converted to backslashes for MSVC tools. Consider adding PathHelper.fix_slashes() to the path function or applying it to the deps before passing them to paths().

Suggested change

	path = path |> String.replace(~S("), ~S(\")) |> Path.expand()
	path =
	path
	|> String.replace(~S("), ~S(\"))
	|> Path.expand()
	|> PathHelper.fix_slashes()
