This commit adds the default .usdz export capability. The importer already supports usdz so no change is required other than updating the text in menu to match the updated exporter text. On export, a .usd/a/c file has to be created first, and then converted to .usdz. A weird change of directory is required because of a quirk with the USD conversion to usdz. If an absolute filepath is passed into the `UsdUtilsCreateNewUsdzPackage` function, the usd files inside the usdz archive will have the same directory structure, i.e. if one tries to create a file at `C:\code\BlenderProjects\file.usdz`, when the usdz file is created, inside it will have the structure `\code\BlenderProjects\file.usdc`. This is counteracted by setting the current working directory to the temporary session directory where both the usdc and usdz files are created, and just passing the file name to `UsdUtilsCreateNewUsdzPackage` without any filepath. Once the usdz file is created it is moved to the intended directory. There is a separate `UsdUtilsCreateNewARKitUsdzPackage` capability for exporting usdz for iOS devices that will be implemented in a follow up patch as it will require some more small UI changes.
