Fix document title with LINE SEPARATOR/PARAGRAPH SEPARATOR/LINE TABULATION

Fix document title with LINE SEPARATOR/PARAGRAPH SEPARATOR/LINE TABULATION

This fix is to align document title with FF(IE fails) and spec.

From the spec, "it must replace any sequence of one or more consecutive
space characters in that string with a single U+0020 SPACE character".
Here "space characters" refer to "U+0020 SPACE, U+0009 CHARACTER TABULATION
(tab), U+000A LINE FEED (LF), U+000C FORM FEED (FF), and U+000D CARRIAGE
RETURN (CR)".
U+2028 LINE SEPARATOR/ U+2029 PARAGRAPH SEPARATOR/ U+000B LINE TABULATION
are not listed and should be supported in title.

Note, for case fast/dom/Document/document-title-get.html there still exists
inconsistency among IE/FF(Win)/FF(Ubuntu).
IE:         FAIL document.title should be one\u000b\u000c
space. Was one space.
FF(Win):    FAIL document.title should be one\u000b\u000c

I don't see the test case in the patch, and document.title-05-expected.txt gives
me a Rietveld error.  Possibly something wrong with the upload?

Can you use named constants for these instead of magic numbers?  Also link to

When click "view" links of document.title-05-expected.txt,  will get "Bad
content. Try to upload again".
Even in patch set 3, this Bad content still happens.
I found similarity issues like this, I didn't know what's happened:
https://codereview.chromium.org/742293002#msg6(Zhang Lei fixed this)
https://codereview.chromium.org/1887233004/#ps90001(Elliot Glaysher not fix
this)
https://codereview.chromium.org/27220005

And after rebase, nothing conflicts. Do you have any hints for this?
