ign to gz : Remaining Files, and Python Libraries/Namespaces

[methylDragon]

See: #698

These should be rebase merged!! Files were moved

Also, this depends on:

• ign -> gz CMake, Config, and Example Files migration : gz-cmake gazebosim/gz-cmake#274
• ign -> gz Migrate Internal CMake Vars : gz-cmake gazebosim/gz-cmake#277
• ign -> gz Shared Lib Migration : gz-launch gazebosim/gz-launch#170

Description

• Moves any remaining files in ign related directories (that aren't redirection headers) or ign related files, and makes the appropriate source changes
• Retargets github workflows
• libignition -> libgz
• These completes the CMake variable/option migration
• Also includes a lot of docs changes (more or less ALL of the ign- type migrations)
• Installs symlinks for python files, allowing use of ignition. instead of gz., but migrates all python usage to ignition.
