Revert of [Reland] Setup LayoutMenuList to not modify layout tree outside style recalc. (patchset #1 id:1 of https://codereview.chromium.org/1150303003/)

Reason for revert:

BrowserTest.CancelBeforeUnloadResetsURL
NaClBrowserTestPnacl.PnaclExceptionHandlingDisabled
PasswordManagerBrowserTest.NoPromptForFailedLoginFromSubFrameWithMultiFramesInPage


Original issue's description:
> [Reland] Setup LayoutMenuList to not modify layout tree outside style recalc.
> 
> This CL updates the LayoutMenuList code to not modify the layout
> tree ourside of style recalc. The way this is done is, instead of creating
> and destroying LayoutText or LayoutBR elements it just uses
> LayoutText elements and sets the blank string into them when
> it would have used LayoutBR previously.
> 
> This CL was originally landed in r195671 but was reverted in r195695 due to
> breaking Android accessiblity tests during the blink roll. The two broken tests
> were:
>  * DumpAccessibilityTreeTest.AccessibilityOptgroup
>  * DumpAccessibilityTreeTest.AccessibilitySelect
> 
> Those tests have been marked as skip, needs rebaseline in
> https://crrev.com/20d41b01d06a8420829a9406eaee773e11239c78
> so this should be safe to reland.
