In some cases, e.g. mouse event, we need to request an animation-only restyle
to force flush all throttled animations when we handle an event with
coordinates. This restyle shouldn't trigger a normal restyle, and add a
different traversal flag, TraversalRestyleBehavior::ForAnimationOnly, to check.
We add one FFI, Servo_GetProperties_Overriding_Animation, which calls
StrongRuleNode::get_properties_overriding_animations() to get a LonghandIdSet,
which may override animation properties running on compositor.
This enum type used to contain the result of parsing
one CSS source declaration (`name: value;`) and expanding shorthands.
Enum types are as big as the biggest of their variant (plus discriminant),
which was quite big because some shorthands
expand to many longhand properties.
This type was returned through many functions and methods,
wrapped and rewrapped in `Result` with different error types.
This presumably caused significant `memmove` traffic.
Instead, we now allocate an `ArrayVec` on the stack
and pass `&mut` references to it for various functions to push into it.
This type is also very big, but we never move it.
We still use an intermediate data structure because we sometimes decide
after shorthand expansion that a declaration is invalid after all
and that we’re gonna drop it.
Only later do we push to a `PropertyDeclarationBlock`,
with an entire `ArrayVec` or nothing.
In future work we can try to avoid a large stack-allocated array,
and instead writing directly to the heap allocation
of the `Vec` inside `PropertyDeclarationBlock`.
However this is tricky:
we need to preserve this "all or nothing" aspect
of parsing one source declaration,
and at the same time we want to make it as little error-prone as possible
for the various call sites.
`PropertyDeclarationBlock` curently does property deduplication
incrementally: as each `PropertyDeclaration` is pushed,
we check if an existing declaration of the same property exists
and if so overwrite it.
To get rid of the stack allocated array we’d need to somehow
deduplicate separately after pushing multiple `PropertyDeclaration`.

We need another flag that represents allow-negative-number for SMIL, so
this enum will also comprise the another parsing mode that allows negative number.

This is mostly a mimic of what we do in
GeckoCSSAnimationBuilder::FillInMissingKeyframeValues().
In Gecko we iterate over the properties just once because we can take the
index for both the synthesized start and end keyframe and easily look them up
as needed. However, in this patch we synthesize the start and end keyframes
separately and iterate over the properties twice because that's easier than
getting two indices and then later calling another FFI to dereference each of
them, and neater than getting back two pointers
Support for Android armv7 and aarch64 target triples
<!-- Please describe your changes on the following line: -->
Support for Android armv7 and aarch64 target triples in python build scripts (build + packaging)
`--android` build parameter works as always (arm-linux-androideabi still the default)
`./mach build --release --android`
New compilation modes for android
`./mach build --release --target=arm-linux-androideabi`
`./mach build --release --target=armv7-linux-androideabi`
`./mach build --release --target=aarch64-linux-android`
See https://github.com/servo/servo/issues/11921. When all crates are ready we'll switch default android compilations to` armv7-linux-androideabi` target triple.

style: Slim down SharedStyleContext, and do various other cleanups around the style crate.
This slims down SharedStyleContext, in preparation for a few things.
First, I would like to eventually move the stylist to the document in Servo, in
order for it to hold the StyleSheetSet.
Also, this gets rid of a fair amount of overhead while creating it in stylo.
Fixes bug 1363245.
