[anchor-position] Implement basic behavior of anchor-center

This patch implements the basic behavior of anchor-center, which is
to center-align the element with its default anchor.

The following are not implemented yet and are for future patches:

  • anchor-center in container's align-items or justify-items values
  • Calculation of the inset-modified containing block
  • Behaviors when overflowing the containing block
