fix(autoware_map_height_fitter): find PCL package after autoware_package() is called

[mitsudome-r]

Description

This package fails to build with the autoware_utils 1.1.0.
(This package depends on autoware_utils via autoware_lanelet2_extension)

Since autoware_utils is now depending on pcl as well, it overwrites some of PCL related CMAKE variables.
In order to only import intended modules, PCL should be included after calling autoware_package().
