Rewrite lower level details of extracting text from page
The current implementation of text extraction was difficult to
understand, duplicated logic that existed in other methods, and wasn't
clear about the units the inputs were in. It also didn't handle
control characters correctly.
The new implementation leans on the methods for converting indices
between the text buffer index and character list index spaces to avoid
duplication of code. It also makes it clear to the reader that inputs
are in the character list index space. Finally, it fixes issues being
seen in Chrome with respect of ranges being slightly off.
This CL also adds a test for extracting text that has control
characters.
