Add width and height params to static if mask

[renan028]

Description

AB#34075

We want to use the mask in a specific area, but that is not possible currently because static layer expands the costmap to be the whole incoming map.
Therefore, if we add it as a plugin like this:

plugins:
  - {name: obstacle,        type: "costmap_2d::ObstacleLayer"}
  - {name: static,          type: "costmap_2d::StaticLayer"}

And if we specify width and height, static will ignore anyway and expand to the map size.
I am adding the flexibility to use given width and height for mask case.
