Convert editing/spelling/spelling-huge-text.html with spellcheck_test 

This patch converts the layout test with spellcheck_test as a
preparation for implementing idle time spellchecker.

This patch also contains a performance optimization to spellcheck_test
in handling CharacterData nodes with long text.

Text to check is divided into chunks to make sure checking some huge text does not freeze the page/UI. With the asynchronous spell checker the whole text is checked. To test manaully trigger spell checking of the editable (e.g. by copy+paste) with unified and asynchronous checker on. There should be 6 misspellings marked.
On success, you will see a series of "PASS" messages, followed by "TEST COMPLETE".
PASS internals.markerCountForNode(testEditable.childNodes[0], "spelling") became 6
PASS successfullyParsed is true
TEST COMPLETE
