Cleanup basic shape code
<!-- Please describe your changes on the following line: -->
I began with isolating serialization stuff for `BorderRadius` to help #16340 and #16352, but ended up cleaning a lot of code in `basic_shape.rs` (it's just a cleanup, should be easy to review)

Limit traversal statistics dumps to subtrees of 50 or more elements and add more values.
On Gecko, we get tons of console spam from 1-element traversals if we don't do this.

This includes the new border code path for simple (solid) borders.
This gives much higher quality border rendering, including proper
support for elliptical border segments.
The quality on https://github.com/servo/servo is noticeably improved.

Overwrite default RunInfo values with the first real ones encountered.
TextRunScanner::flush_clump_to_list compares the values in the RunInfo object against the ones determined from the current fragment, but these values can be arbitrary defaults that don't mean anything useful.

style: Fix dynamic changes of attributes when combined with :not.
This makes the dependency tracker properly recurse into simple selectors inside the current complex selector to find the appropriate dependencies.
We can't still remove the outer visitor because we need it for stuff like `:not(.foo + bar)`, but I plan to get rid of it in a followup as long as try comes back green.

It's clearly wrong to use intersects() there, since the coming check may be a
bigger hint.

Add env var for local saltfs root during bootstrap
<!-- Please describe your changes on the following line: -->
This enables using the environment variable `SERVO_SALTFS_ROOT` to use a local copy of the saltfs tree for `./mach bootstrap`. The immediate use case is to add a test for `./mach bootstrap` to saltfs itself, to ensure Salt changes or refactors don't break `./mach bootstrap`.
I tested this locally in an Ubuntu Trusty VM.

Implement alignment shorthand properties
<!-- Please describe your changes on the following line: -->
I implemented the shorthand properties, but it may includes some bugs.
Currently, `mach test-unit -p style` caught some errors (see #15954). I already tried `mach build-geckolib`, though there is no improvement. Please check my code.
