the project root and engine root to fix issues with running the Editor
or AssetProcessor from within the project folder overriding the
project_path with the engine root bootstrap.cfg project_path entry
The order in which the project path is overridden as follows
1. The <engine-root>/bootstrap.cfg is first merged into the Settings
Registry. Any '/Amazon/AzCore/Bootstrap/project_path' would be used
if the following steps don't override that key.
2. Followed by general *.setreg/*.setregpatch files being merged into
the Settings Registry which can override the
'/Amazon/AzCore/Bootstrap/project_path' key
3. Next a project.json file searched upwards from the current executable
directory to determine the project path
4. Finally if a command line parameter that overrides the project path
is supplied it is used instead
