Zachary D. Rowitsch 4d2b62f596 Fix three layout bugs: nobr inline display, block-in-inline split ordering, and BFC-only float avoidance
Three bugs caused Google's homepage to render incorrectly (elements at 0,0
or pushed off-screen):

1. <nobr> defaulted to display:block instead of inline, inflating float
   shrink-to-fit widths to the full viewport.

2. normalize_children ran before split_block_in_inline, wrapping inline
   elements in anonymous blocks before the splitter could find them.

3. Float avoidance applied to non-BFC blocks instead of BFC blocks
   (condition was inverted per CSS 2.1 §9.5).

Also implements CSS 2.1 Appendix E paint order: floats now paint after
normal flow block backgrounds via multi-phase rendering in the display
list builder. Positioned elements act as mini stacking contexts and
don't propagate skip_floats to their children.

Net result: +10 WPT tests passing (11 promoted, 1 minor regression).
