Fix a crash in AILanguageDetectorFactory::capabilities() called on a detached frame

• Add [RaisesException] EA to AILanguageDetectorFactory::capabilities(), raise an exception when no execution context is present;
• See if execution context is available before calling GetLanguageDetectionDriverRemote()
• Add a CHECK() within GetLanguageDetectionDriverRemote() to enforce that.

Add CSS Color 4 gradient options to CanvasGradient

Add ColorInterpolationMethod, HueInterpolationMethod and
premultipliedAlpha attributes to CanvasGradient as described here:

whatwg/html#7947

This is done behind the flag CanvasGradientCSSColor4, as spec is not yet
settled:

whatwg/html#10986

Gradient::ColorInterpolation is also renamed to
Gradient::PremultipliedAlpha, because that's what it is.

Subpixel antialiasing for test labels is being inconsistently applied on
windows, so the tests are marked as failing with a bug.

Implement the Canvas TextStyles lang attribute

The HTML canvas textStyle "lang" attribute provides control over the
locale when using text features in a canvas. The default is "inherit"
that takes the language from the host document element. Other strings
are used directly as a locale.

Make name: and code: required parameters in the canvas test generator

In the process of documenting the test generator, it's useful to clarify
which parameters are required and which ones are optional. The only two
required parameters are 'name:' and 'code:'.

Add an img_reference reftest type in canvas WPT test generator

In the process of documenting the test generator, all template
parameters should have a clear purpose that can be explained. The
templates used to generate the test files use the parameter
'img_reference'. This parameter is populated by the test generator,
using the filename of the image generated when using 'cairo_reference'.
Seeing that the variable exists, users of the test generator could be
tempted to use it. We must therefore decide whether we should allow
this or whether we should make this a reserved internal parameter.

Allowing the use of this parameter could actually be useful. Tests
could use it to test against solid color images, like
'/images/green-100x50.png'. This would be much better than how lots of
tests currently specify 'expected: green' in their definition. The
images specified with 'expected:' are not used by the test runner to
check the test result, but 'img_reference' is.
