[ALOY-709] Add ability to disable auto adding "classes" and "apiName" properties

Adding "classes" and "apiName" imposes overhead on the creation of Titanium UI components, as detailed in ALOY-706. "apiName" will eventually be solved by the tickets resulting from TIMOB-12553, but "classes" will continue to pose a performance issue until we have the core runtime. The use of dynamic styling may not be desirable for all developers and they should not be forced to incur those performance costs. We need to make dynamic styling optional at a project-level in the config.json and perhaps investigate allowing it to be used on a per-component level. The new autoStyle option can be set to either true or false.

project-level

This will add auto styling for all markup components. If autoStyle is not specified, it is false by default.

config.json

{
    autoStyle: true
}

controller-level

All components within this controller would be auto styled. Overrides project-level option.

<Alloy autoStyle="true">
    <!-- the rest of your components -->
</Alloy>

component-level

The specific component with autoStyle would be automatically styled. This overrides both project and controller level options.

<Alloy>
    <Window>
        <Label autoStyle="true">some label</Label>
    </Window>
</Alloy>
