function FilterAPITest::testProcessedTextElement

Tests the 'processed_text' element.

Function check_markup() is a wrapper for the 'processed_text' element, for use in simple scenarios; the 'processed_text' element has more advanced features: it lets filters attach assets, associate cache tags and define #lazy_builder callbacks. This test focuses solely on those advanced features.
