IDL: Support [DeprecateAs] and [MeasureAs] on constants

For constants with [DeprecateAs] or [MeasureAs], create the property
using v8::Template::SetNativeDataProperty() instead, using a simple
accessor callback function that handles the deprecation/measuring and
returns the constant value.

Don't crash when an image fails to decode.

The code that extracts the image for the default frame from an animated
bitmap should check that the image data is actually available.
It is possible for decoding to fail for invalid frames, Blink should not
crash when this happens.
