* Creating Builder variant aliases for all Asset Gems
* Added an AssetGem template for creating an Asset Gem
The AssetGem template is meant for non-code Gems
* Updated the engine_template.py commands to use pathlib
Each of the four commands: create-template, create-from-template,
create-project and create-gem have been updated to use pathlib.Path or
any path manipulation
Fix several python errors when instantiating a template with missing
o3de objects.
For example attempting to use the create-project command with the
"DefaultGem" template would result in a python exception instaed of a
error log and a return value 0..
Added a **force** option to the engine_template commands
to force overriding of existing files
* Optimized search through text files when the create-template command is
run when attempting to replace the license text section
* Adding a Minimal Project Template that contains the minimal set of gems
as stated by UX
* Minor changes to the DefaultProject template. Added a license section to the EngineFinder.cmake
* Adding the MinimalProject to the engine.json file
