This change adds support for `position: relative` to table `<caption>`.
In addition to adjusting their position according to inset values, table
captions must also establish containing blocks for descendants that are
absolutely positioned.

If we encountered a preserved line break after some whitespace, we were
including the space in the max-content size of the following line.
So just like `line_break_opportunity()` was already clearing
`self.pending_whitespace.min_content`, `forced_line_break()` needs to
clear `self.pending_whitespace.max_content` too.
Also some cosmetic refactoring.

This change removes the `effective_writing_mode` concept and tries to
properly implement right-to-left layout support for all non-inline
writing modes. In general, what needs to happen is that rectangles
need to be converted to physical rectangles using the containing block.
A right-to-left rectangle's inline start is on the right physical side
of the containing block. Likewise a positive inline offset in
right-to-left text is a negative physical one.
The implementation here is pretty good for most layout modes, but floats
are still a bit in process. Currently, floats are processed in the
logical layout of the block container, but there still might be issues
with float interaction with mixed RTL and LTR.
While this does move us closer to supporting vertical writing modes,
this is still unsupported.
New failures:
- Vertical writing mode not supported:
- `/css/CSS2/floats/floats-placement-vertical-001b.xht`
- `/css/CSS2/floats/floats-placement-vertical-001c.xht`

`white-space: break-spaces` should allow a soft wrap opportunity *after*
every preserved white space. Then, to avoid breaking before the first
white space, `TextRunSegment::shape_text()` has some logic to separate
it from the following spaces and put it with the preceding text instead.
The problem was that, when combined with `word-break: keep-all`, we were
then only checking whether there were more white spaces afterwards,
ignoring the soft wrap opportunity after the first one.
Also removing a duplicated `can_break_anywhere` variable.

We weren't moving a table-header-group to the front if it was the first
row group. However, there might still be preceding rows that don't
belong to any row group.
And similarly, we weren't moving a table-footer-group to the end if it
was the last row group. However, there might still be following rows
that don't belong to any row group.
This patch fixes the logic, and enables existing tests from Microsoft

This changes converts all input element parsing and normalization to use
`time` instead of `chrono`. `time` is used by our dependencies, so it
makes sense to work toward removing the Servo dependency on chrono.
In addition, parsing and normalization also moves to a trait on &str to
prepare for the possibility of all script parsers moving to a separate
crate that can have unit tests written against it.
Code duplication is eliminated when possible and more conversion is done
using integer types. These two things together mean we pass more tests
now.

Up until now, Servo was using a very old version of time to get a
cross-process monotonic timestamp (using `time::precise_time_ns()`).
This change replaces the usage of old time with a new serializable
monotonic time called `CrossProcessInstant` and uses it where `u64`
timestamps were stored before. The standard library doesn't provide this
functionality because it isn't something you can do reliably on all
platforms. The idea is that we do our best and then fall back
gracefully.
This is a big change, because Servo was using `u64` timestamps all over
the place some as raw values taken from `time::precise_time_ns()` and
some as relative offsets from the "navigation start," which is a concept
similar to DOM's `timeOrigin` (but not exactly the same). It's very
difficult to fix this situation without fixing it everywhere as the
`Instant` concept is supposed to be opaque. The good thing is that this
change clears up all ambiguity when passing times as a `time::Duration`
is unit agnostic and a `CrossProcessInstant` represents an absolute
moment in time.
The `time` version of `Duration` is used because it can both be negative
and is also serializable.
Good things:
- No need too pass around `time` and `time_precise` any longer.
`CrossProcessInstant` is also precise and monotonic.
- The distinction between a time that is unset or at `0` (at some kind
of timer epoch) is now gone.
There still a lot of work to do to clean up timing, but this is the
first step. In general, I've tried to preserve existing behavior, even
when not spec compliant, as much as possible. I plan to submit followup
PRs fixing some of the issues I've noticed.
