Calvin a57c3d9801 Fix string literal parsing escaped whitespace (#2617 )

The toolchain misinterprets escaped whitespace characters as unescaped when trimming trailing whitespace on a line. This PR adds a variable to track the length of the string after escaping the most recent escape, making sure we don't backup past that character, whatever it is.

I did try the approach mentioned in #2132 of not backing up `end_of_regular_text` number of characters, but this caused problems on lines like <kbd>tab</kbd> <kbd>space</kbd> <kbd>tab</kbd> (those characters literally, not escaped) where it would leave the first tab since that is processed in a different iteration of that loop.

I added a test case for this bug. I kept getting mixed up in the test output which one was the expected value, so I also changed a variable name there for clarity.

Fixes #2132.
