🎉 New feature

Part of #350

Summary

Using GzPython.cmake to find python is not ideal since it's best to find python once with the components that you need. Now that find_package(Python3) works well, it's best to just use that.

All Gazebo packages in Ionic have stopped using GzPython, so this should be safe to merge.

Test it

Compile Gazebo Ionic from source against this branch and ensure there are no cmake warnings from using GzPython and that python bindings are properly built for each package.

Checklist

  • Signed all commits for DCO
  • Added tests
  • Added example and/or tutorial
  • Updated documentation (as needed)
  • Updated migration guide (as needed)
  • Consider updating Python bindings (if the library has them)
  • codecheck passed (See contributing)
  • All tests passed (See test coverage)
  • While waiting for a review on your PR, please help review another open pull request to support the maintainers

Note to maintainers: Remember to use Squash-Merge and edit the commit message to match the pull request summary while retaining Signed-off-by messages.

It's better to call find_package(Python3) directly so the
user has better control over which COMPONENTS are requested.

I just noticed some uses of PYTHON_EXECUTABLE; I'll clean those up before merging this

primarily here: https://github.com/gazebosim/gz-sim/blob/main/python/CMakeLists.txt#L12

that's old cmake code that will be removed as part of #350, so actually it shouldn't be a problem
