Include target attributes in the attributes comparator

[kwridan]

Resolves #62

Overview

• Target attributes are now included in the comparison results of the attributes comparator
• Each target will now have a dedicated comparison result

e.g.

❌ ATTRIBUTES > "MyTarget" target

⚠️  Only in second (1):

  • LastSwiftMigration = 1110

• Target attributes may contain references to other targets, to ensure a semantic comparison is performed a target lookup is performed on attributes and resolved to their names if necessary
• A typical example is when setting a target application for a UI test target which sets the TestTargetID attribute

TargetAttributes = {
    3704EABFFE3515E47749586D = {
        CreatedOnToolsVersion = 12.5;
        TestTargetID = 76EC5DF0EEA681734B20EC5C; /* <--- Reference to another target */
    };
    76EC5DF0EEA681734B20EC5C = {
        CreatedOnToolsVersion = 12.4;
    };
};

• An additional fixture was added to contain projects with UI test targets which have target applications set. The underlying raw references are not identical, but are semantically equivalent (MyAppUITests > MyApp)

Test Plan

• Run xcdiff on the fixtures

cd Fixtures
swift run xcdiff -g attributes -v

• Verify target attributes are now included in the results
• Run xcdiff on the new ui test fixtures

cd Fixtures/ios_project_with_ui_tests
swift run xcdiff -g attributes -v

• Verify the TestTargetID attribute is not flagged as a difference
