fs: add Deno.utime(...)/Deno.utimeSync(...)

[kevinkassimo]

Closes #1948.

function utimeSync(
  filename: string,
  atime: number | Date,
  mtime: number | Date
): void;

async function utime(
  filename: string,
  atime: number | Date,
  mtime: number | Date
): Promise<void>

Notice utime (instead of utimes) means that atime and mtime have resolution of 1 second (epoch time format). (Linux manpages)

• Node: fs.utimes(path, atime, mtime, callback)
  • Node seems to be also using resolution of 1 second, but named as utimes (using libuv uv_fs_utime).
• C: int utime(const char *filename, const struct utimbuf *times);
  • utimbuf uses resolution of 1 sec
• Go: func Chtimes(name string, atime time.Time, mtime time.Time) error
• Python: os.utime(path, times=None, *, [ns, ]dir_fd=None, follow_symlinks=True)

Need help with windows deps fix (as I do not have a windows machine to experiment)
nvm, figured out myself how to do this after reading code from rust.gni

LGTM - i'm kinda surprised this isn't in Rust's standard lib. Nice work as always.
