Add mask combination method

[renan028]

Description

part of: AB#17228

• Instead of using flag use_maximum_, use the combination method
• Add a new combination method for static layer: Mask

The idea is to be able to subtract the static layer from the costmap, so that we use only the obstacle layer, without the static obstacles (map). Video below.

Note that the plugins order matter. In this case, we should use:

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

@renan028 do we still need this?

I will change this to Mask and fix because it changes to the whole map.
