This reverts commit 08662f0575.
Reason for revert: failure on pkg-win-release, https://dart-ci.appspot.com/log/pkg-win-release/unittest-asserts-release-win/12878/pkg/dartdev/test/commands/test_test
Original change's description:
> Enable long path on Windows
>
> File APIs on Windows can now handle files and directories identified by
> long paths (greater than 260 characters). For directory, the limit is
> 248.
>
> Some restrictions from Windows:
> 1. The size limit for long path is 32,767 characters.
> 2. Each component separated by backslashes should not be more than 255
> characters.
>
> Reference: https://docs.microsoft.com/en-us/windows/win32/fileio/naming-a-file#maximum-path-length-limitation.
>
> Note that `Directory.current` does not work with long path.
>
