Only load dynamic preload data when needed

[seadowg]

Closes #5620
Blocked by #5665
Blocked by getodk/javarosa#733

Uses the newly added XFormParser.XPathProcessor to detect pulldata or search in forms and only if they are present create the database needed for them.

Why is this the best possible solution? Were any other approaches considered?

This is a direct follow on from #5665 where most of the structure was defined - all I've done here is integrate XFormParser.XPathProcessor to properly implement DynamicPreloadParseProcessor.

How does this change affect users? Describe intentional changes to behavior and behavior that could have accidentally been affected by code changes. In other words, what are the regression risks?

Users should no longer see the "Pre-loading data from" loading state when opening a form with a secondary instance for the first time unless it contains a pulldata or search function. It'd be good to test forms with and without these functions to check that everything works as expected, and that the first load is now faster for forms that don't include search/pulldata.

Before submitting this PR, please make sure you have:

• added or modified tests for any new or changed behavior
• run ./gradlew checkAll and confirmed all checks still pass OR confirm CircleCI build passes and run ./gradlew connectedDebugAndroidTest locally.
• added a comment above any new strings describing it for translators
• verified that any code or assets from external sources are properly credited in comments and/or in the about file.
• verified that any new UI elements use theme colors. UI Components Style guidelines
