Account for the font of empty input fields
The font of empty fragments is not accounted for in layout. This behavior is incorrect when part of an input field.

Fragment debug_id u16 only exists in debug, prod will format mem address
<!-- Please describe your changes on the following line: -->
Each fragment has a `u16` `debug_id` in debug mode, but no `debug_id` in production to save memory. To format a debug id in production, the address of the empty `debug_id` is displayed.

Do not create stacking contexts for text fragments
Without this change, each text fragment in a block that establishes a
stacking context will establish its own stacking context. This is
unnecessary and increases the amount of work done during display list
construction. This change should not change output, but should improve
performance.

Support remaining longhand flexbox style properties for servo
- [x] `./mach build -d` does not report any errors
- [X] `./mach test-tidy --faster` does not report any errors
- [X] There are tests for these changes
Add the remaining longhand CSS properties of flexbox for servo,
including `flex-wrap`, `flex-grow`, `flex-shrink`, `justify-content`,
`align-items`, `align-self` and `align-content`.
Tests for the remaining longhand properties are also enabled. Test for
default value of `align-self` is modified because the new default value
for this property is "auto" is current flexbox CR.

WebRender.
This happens asynchronously, just as it does in non-WebRender mode.
This functionality is a prerequisite for doing proper display-list-based
hit testing in WebRender, since it moves the scroll offsets into Servo
(and, specifically, into the script thread, enabling iframe event
forwarding) instead of keeping them private to WebRender.
Requires servo/webrender_traits#55 and servo/webrender#277.
Partially addresses #11108.
The previous code assumed that the diagonals of the elements were
perpendicular, which only happens with squares.
