[@scope] Pass TreeScope separately to SelectorChecker

The scope member of SelectorCheckingContext is currently used
for several closely related (but different) things, causing subtle
bugs and a hard-to-understand model.

To address this, pass the TreeScope to SelectorChecker separately,
and use context.tree_scope for ShadowRoot-dependent decisions
in selector matching.

The context.scope field is now only used for two things:

1. For matching the :scope pseudo-class.
2. For creating the default activation for @scope.

This fixes Issue 377647716, because since we no longer "clobber"
context.scope during scope activation, making ParentElement
traverse to the shadow host.

Make ConsumeNumberOrPercent() not crash on unresolvable calc().

Instead of calling GetDoubleValue() on percentage calc expressions,
we just return them directly, and then add a new rule saying that
ComputeNumber() on them returns the percentage value divided by 100.
This avoids crashes when we try to force them during parsing.

This also takes us halfway towards fixing the opacity-valid.html test;
we no longer convert it into just a double (without surrounding calc()),
but since we don't properly simplify comparison expressions containing
percentages, we don't simplify as much as we should either, so the test
is still broken. (And even after that, we'd probably need to convert
percentages to decimals inside calc for such properties.)

[@container] Add support for scroll-state(overflowing) axis

Add new values for matching axis instead of edge for overflowing: block,
inline, x, y.

These are convenience keywords. For instance:

scroll-state(overflowing: x)

is the same as:

scroll-state((overflowing: left) or (overflowing: right))

Prevents for h264 attaching SPS and PPS Nalu if already present on Windows

This patch prevents adding the SPS and PPS present in extradata WMFMediaDataEncoder,
if the data already contains SPS and PPS. Otherwise, the resulting Byte stream would
not be spec complained and be rejected by Chromium, for example.
It also includes a WPT test.
