Migrate user agent string to `Cow<'static, str>`.
In most scenarios, where the user of Servo will not override the default
user agent, the user agent can be a `&'static str`. But since we allow
for customization, we currently use a `String` to represent the user
agent. This commit migrates the user agent to be represented as a
`Cow<'static, str`, which (at the cost of ergonomics) prevents
unnecessary allocations whenever cloning the user agent string in the
scenario the user doesn't override the user agent.

layout: Don't use the existing block position as the float ceiling when placing block formatting contexts in the sequential fallback.
The existing block position isn't yet computed at that time, so it
contains junk data. It just so happened to work on first reflow because
that value is usually set to zero, but it usually failed on subsequent
reflows.
Improves certain Wikipedia pages.
Closes#13630 (though Google is still broken; it was a separate bug and
will be split off into a separate issue).

Refactor style logic to avoid direct access to the node data during the cascade
The new restyle architecture doesn't store these things in consistent places, so we need a more abstract API.

Pipeline always stores frame

This change makes the pipeline always store the frame id, not just optionally. This is the first part of a long slog to use FrameIds rather than PipelineIds to identify frames. cc @ConnorGBrewster

Don't pref-gate properties in geckolib mode
This led to me wasting a lot of time trying to figure out why my column-count implementation in gecko didn't work.
We might eventually want to hook into the Gecko prefs, but the mechanism would probably be different

These new functions are derived from the existing uniform*fv
functions. They get used in a lot of demo code, so it should greatly
improve our compatibility.
This regresses uniformMatrixBadArgs.html, which gets at an existing
problem in our uniform matrix support (failure to validate
that the uniform is a matrix before calling down) but previously just
failed because it only called the 'fv' variants and never the existing
'f' variants.

The current semantics make it very difficult to figure out when the existing
style is mutated and what code depends on it. This is problematic for the
new incremental restyle architecture, where the cascade logic no longer has
direct access to |data|.
