Windows colcon: Rename ignition package to gz if not in ws

[chapulina]

• Part of CMake project names from ignition to gz #718

We need to support Citadel and Fortress ignition- packages, as well as Garden gz- packages.

The logic here checks if colcon can detect the ignition- package in the workspace, and if it can't, it renames the package to gz- and tries that.

Test runs:

• With gz-, using Rename CMake project to gz gazebosim/gz-utils#57: https://build.osrfoundation.org/job/ign_utils-pr-win/225/console#console-section-6

# BEGIN SECTION: Update package ignition-utils2 from ignition to gz if needed
Packages in workspace:
gz-cmake3
gz-utils2

gz-utils2
Using package name gz-utils2
# END SECTION

• With ignition-, using ign-utils1 branch: https://build.osrfoundation.org/job/ign_utils-pr-win/227/console

# BEGIN SECTION: Update package ignition-utils1 from ignition to gz if needed
Packages in workspace:

ignition-cmake2
ignition-utils1
ignition-utils1
ignition-utils1
Using package name ignition-utils1
# END SECTION
