Bard fields augment multiple times with runtime Antlers parser

[jacksleight]

Bug description

When using the runtime Antlers parser I'm seeing Bard fields being augmented/rendered multiple times, despite only being output once. I'm checking this by calling dump in the Statamic\Fieldtypes\Bard\Augmentor::convertToHtml method.

With the regex parser that method is only called once per output, with the runtime parser it's called three times.

Given that Bard fields can contain a large amount of content when used as page builders etc. this could have a significant performance impact.

How to reproduce

1. Create a Bard field, add some content and output it in a template.
2. Log the number of times the Bard Augmentor is run.

This is something I've been looking into with this work here: https://github.com/statamic/cms/pull/5783

Internally there are a number of places where a value may be resolved to determine what to do with the data:

• An existence check: to help decide if something should be executed as a tag or variable
• Checking for query builder instances to decide if they should be intercepted and ran through the query tag
• Finally when resolving the value to actually produce output

I'll look into other improvements while that PR is reviewed/discussed 👍
