    Windows: Added internal `fullpath` API to normalize paths.

    This explicitly does not check for existence, nor does it follow
    symlinks. It simply normalizes a given path to an absolute path. This
    removes the `reparsepoint.hpp` and `symlink.hpp` dependency os
    `os::realpath`.

> `os::realpath` on Unix should error out if the path does not exist. On Windows, the implementation is backed by `_fullpath`, which does not error out if the path does not exist. In general, we'd like the semantics to be as similar as possible across the two.
