Bug fixes and performance improvements for the ParallelPixelProcessor

[DanielJette]

What does this change accomplish?

• Add parallelThreads extension property to the Gradle plugin. This allows for customization of the number of worker threads to be used by the ParallelProcessor. Set limits on the thread pool to a minimum of 1 and a maximum of 4.
• Refactor the ParallelPixelProcessor and introduce a new configuration class to wrap the thread configuration variables and the CoroutineDispatcher configuration.
• Several small improvements to the FuzzyCompare method to perform fewer allocations inside the analyze function
• Upgrade UiAutomator dependency to 2.3.0 https://developer.android.com/jetpack/androidx/releases/test-uiautomator
• Recycle the bitmaps in the finalize block of assertSame()
• Add several new tests and enhancements to the existing ParallelProcessor tests
• Upgrade the compile SDK for the samples to 34

Scope of Impact and Testing instructions

• The existing tests should sufficiently verify that there are no regressions.

Looks like this last rebase has a legit test failure.

Yes, I noticed that. There's definitely a logical conflict between this PR and what was in the ScenarioRule changes. I'll address these failure and push up a fix.
