We want to use a similar model as Chrome on Android does for scaling our display of web content, that is use font inflation for desktop pages and plain text zooming for everything else.
Since we don't want to simply clobber any text zoom that might have been set by the user/front-end code, we allow setting and storing the system font scale separately on the PresContext. We then calculate the effective text zoom value as the product of the system font scale and the current text zoom value.
Any function that is using the PresContext's TextZoom value for layouting/rendering is switched over to this new EffectiveTextZoom value, whereas functions that are interested in the text zoom as actually set by the user/front-end (e.g. the nsDocumentViewer, or the code responsible for copying text and full zoom settings into the new PresContext on page navigation) continue using the plain TextZoom value.
As long as font inflation is enabled in principle (e.g. font.size.inflation.minTwips != 0), every page starts out as eligible for font inflation until the relevant meta viewport tags marking the page as "mobile friendly" have been detected. Since the PresShell caches the font inflation state and only recalculates it when necessary, we make use of that and set the PresContext's system font scale as necessary whenever the font inflation state has been refreshed.

We can remove unnecesasary SMILMappedAttribute and SMILAttrAnimationRuleProcessor since earlier patches in this serieas mean this code is no longer used.

This patch removes handling of the 'attributeType' attribute so that we behave
as if attributeType is always 'auto'. This means that for CSS properties we
always animate them as CSS properties (i.e. we animate them as part of the
SMIL override stylesheet) rather than mapped attributes.
The one special case is width/height on an outer SVG. Previously we animated
this as a mapped attribute since Web compatibility requires that the
width/height on an outer SVG, when set explicitly, are mapped to style.
However, we can produce the same behavior by animating these as CSS properties
(as opposed to mapped attributes). There is no observable difference in results
returned by the SVG DOM APIs, only the level at which the result is added to
the cascade: the SMIL override stylesheet instead of the attribute animation
presentation hint level.
As part of this patch, we animate width/height on outer SVG elements as CSS
properties as opposed to mapped attributes both for consistency and also so
we can remove the animated mapped attribute code altogether.

This changeset will skip finding the first SMIL animation function to affect the sandwich from multiple functions if element hasn't primary frame when composing attributes.
This mean that target element's animation don't need to animate in the following cases.
- ancestor elements has display:none attribute.
- target element have display:none attribute.
- ancestor element's tag produces a non-rendering subtree, by definition (like <desc>).

DOM's initEvent says that it must do nothing during dispatch. UI Events
says they behave the same as initEvent, so the legacy initializers
defined there also shouldn't do anything during dispatch. Previously we
only did this for initEvent itself, but other legacy initializers would
function normally during dispatch.
Edge passes the wpt test that's updated in this commit. Chrome passes
all but initCustomEvent. It would be nice to expand the test to have
coverage for all our legacy initializers, but the likelihood of
real-world compat issues from this behavior is slim enough that I didn't
think it was worth the effort.

The surrounding code in this file and elsewhere uses pairs of RangedPtrs
for iterators. While we're trying to modify nsString's iterators so
they're more like RangedPtr, it seems reasonable to go ahead and modify
this instance of nsString iterators to use RangedPtr directly for
conformity with the surrounding code.
Enable nsAttrValue::EnumTable to be initialized with enum. So, we could get rid
of the castings in EnumTable. Fix EnumTable initialization comment.
For those untyped enumerations, declare them with uint8_t, as to other typed
enumerations with type size larger than int16_t, force casting to int16_t.
Use {nullptr,0} instead of {0} to represent the last entry.

The new name makes the sense of the condition much clearer. E.g. compare:
NS_WARN_IF_FALSE(!rv.Failed());
with:
NS_WARNING_ASSERTION(!rv.Failed());
The new name also makes it clearer that it only has effect in debug builds,
because that's standard for assertions.

hasFeature() always returning true matches the current DOM spec. SVG 2
has removed requiredFeatures. Chrome has had both of these always
return true since 2014, and they seem to have had no problems.
Even requiredFeatures="" (empty string) now returns true, matching
Chrome.

This patch is generated by the following commands (note: if you're running
using OS X's sed, which accepts slightly different flags, you'll have to
specify an actual backup suffix in -i, or use gsed from Homebrew):
hg stat -c \
| cut -c 3- \
| tr '\n' '\0' \
| xargs -0 -P 8 gsed --follow-symlinks 's/\bnsCSSProperty\b/nsCSSPropertyID/g' -i''
Then:
hg mv layout/style/nsCSSProperty.h layout/style/nsCSSPropertyID.h
... and finally, manually renaming nsCSSProperty in the include guard in
nsCSSProperty.h.

This patch makes most Run() declarations in subclasses of nsIRunnable have the
same form: |NS_IMETHOD Run() override|.
As a result of these changes, I had to add |override| to a couple of other
functions to satisfy clang's -Winconsistent-missing-override warning.
