feat: add bindSourceArgs and bindCuratorArgs utility functions

[mityu]

Add utility functions, bindSourceArgs and bindCuratorArgs, to create a new source or curator which calls another source or curator respectively with fixing the head n number of command-line arguments.

For example, suppose if you have pickers defined like this,

definePickerFromSource(
  "runtime-files-1",
  bindSourceArgs(
    builtin.source.file,
    [Deno.env.get("VIMRUNTIME")],
  ),
  ...
)

definePickerFromSource(
  "runtime-files-2",
  bindSourceArgs(
    builtin.source.file,
    async (denops) => [await denops.eval("$VIMRUNTIME") as string],
  ),
  ...
)

then both :Fall runtime-files-1 and :Fall runtime-files-2 will be equivalent to :Fall file $VIMRUNTIME.
Plus, these utility functions does insert given arguments at the head of command-line arguments instead of replacing entire command-line arguments with given arguments, therefore :Fall runtime-files-1 additional-arg will be equivalent to :Fall file $VIMRUNTIME additional-arg (though file source does not accept two or more arguments and this is not actually a valid command).
