cros_next: add MaterialNext dialog (part 2)

This cl follows crrev.com/c/4500464 to implement the auto
adjustment of dialog sizes.

The cl adds a class called SystemDialog to create the dialog
widget parented to a host window and adjust the widget size
according to the host window size.

The resizing rules of the dialog are as follows:
- when host width > 672, dialog width = 512.
- when 520 < host width < 671, dialog width decreases with a
  padding of 80 on both sides.
- when 424 < host width < 519, dialog width = 359.
- when 400 < host width < 423, dialog width decreases with a
  padding of 32 on both sides.
- when host width < 399, dialog width = 296.

The final effecs are shown in the bug comments.
