This is mostly straightforward. I had to modify a couple of places
which were accidentally discarding whitespace.
Fixes#1513.
This fixes some relevant tests from the CSS testsuite... but a lot of
them are either manual, or don't pass because of unrelated issues. (For
example, white-space-mixed-002 renders correctly, but
white-space-mixed-002-ref doesn't because of a float bug.)
I'd appreciate any suggestions for how to go about adding tests for this.

This patch makes Servo unconditionally strip whitespace before text run
scanning (assuming that the `white-space` property allows it). Whitespace
stripping during reflow is now only used for handling whitespace at the ends of
lines; reflow now never attempts to handle ignorable whitespace.
Many CSS tests pass now. There are some new failures, however.
The following reference tests now fail due to a pre-existing bug whereby
whitespace is used to calculate the position of inline hypothetical boxes for
elements with `display: inline; position: absolute`:
* `absolute-replaced-height-036.htm`
* `vertical-align-sub-001.htm`
* `vertical-align-super-001.htm`
The following reference tests fail due to a pre-existing bug whereby we don't
handle `font-size: 0` properly in inline reflow:
* `font-size-zero-1.htm`
* `font-size-zero-2.htm`
The following reference test fails due to the fact that it relied on our
incorrect insertion of whitespace to make room for the black background:
* `inline-formatting-context-007.htm`

This fixes a lot of "jumpiness" and removes the `new_line_pos` stuff.
Closes#2260.

On my laptop, running `./mach test-unit` goes from about 11 minutes to 22 seconds, when run after `./mach build`.

Note that I had to change some expectations to make them pass.

`str::to_string()` goes through a `Formatter`, `str::into_string()` is a direct copy and is apparently 5× faster.
This is a rebase of the boring and bitrot-prone parts of #4366.

This is a grab bag of performance improvements that significantly improve style recalculation, layout, and painting on a few static pages.
Let me know if you'd like me to split this PR up.
