 Tests: Add new `assertEqualHTML` assertion.

 Add a new `assertEqualHTML` method to `WP_UnitTestClass` for tests
 comparing HTML (potentially including block markup).

 Internally, the assertion builds a deterministic tree string
 representation of the markup (using the HTML API) and compares the
 results. The format of the tree is inspired by the HTML5lib-tests tree
 format. It is extended with a special representation of block delimiters
 and their attributes. This format also makes it easier to visually spot
 the differences between the two strings if the assertion fails.

 Finally, this changeset updates `Tests_Dependencies_Scripts` to remove its
 `assertEqualMarkup` and `parse_markup_fragment` methods, and to use the
 newly introduced `assertEqualHTML` instead.

 Props bernhard-reiter, jonsurrell, dmsnell, jorbin, gziolo.
 Fixes #63527.
