Use the size of the containing block, not the size of the block formatting context, to place floats in layout 2020.
The containing block for a float is not necessarily the same as the block
formatting context the float is in per CSS 2.1 [1]:
"For other elements, if the element’s position is relative or static, the
containing block is formed by the content edge of the nearest block container
ancestor box."
This shows up in the simplest case:
<html>
<body>
<div style="float: left">Hello</div>
</body>
</html>
In this case, the `<html>` element is the block formatting context with inline
size equal to the width of the window, but the `<body>` element with nonzero
inline margins is the containing block for the float. The float placement must
respect the content box of the `<body>` element (i.e. floats must not overlap
the `<body>` element's margins), not that of the `<html>` element.
Because a single block formatting context may contain floats with different
containing blocks, the left and right "walls" of that containing block become
properties of individual floats at the time of placement, not properties of the
float context itself.
Additionally, this commit generalizes the float placement logic a bit to allow
the placement of arbitrary objects, not just floats. This is intended to
support inline layout and block formatting context placement.
This commit updates the `FloatContext` and associated tests only and doesn't
actually wire the context up to the rest of layout, so floats in pages still
aren't actually laid out.

Use backtrace fork with UWP-specific fix.
Fixes#27367, which was introduced by 57f4f0a09f. I'd like to do a new release in the store, and I would prefer not to wait for a new version of backtrace to be released before that can happen.
