Now that we no longer have the extra layer of ImageContainers providing
a superficial level of caching/reuse of existing blob recordings, we
need some way to share recordings. This part adds support to
SurfaceCache to store BlobSurfaceProvider objects.
This includes the specialized code for invalidating SVG images. In
particular this is useful for animated SVG images. In general we want to
avoid changing the image key whenever possible so that we avoid
reallocating the underlying buffers in the compositor process for the
rasterized blob images.
We also need to track the ImageIntRegion used by the recording. If a
caller only wants a slice of the SVG image, then we need to track this
differentiation in our cache entries. At this time, we don't allow
substitutes for entries with a region exclusion.

Currently we can only use the gfx.color_management.force_srgb pref to
force all images to sRGB, or just accept device space. It would be nice
to be able to test device space in our tests, as well as sRGB. This
patch adds a surface flag which allows us to selectively output sRGB.
This will also be useful for clipboard and re-encoding purposes, since
they want a neutral output. In an ideal world we would just output the
color profile and the pixel data in the original color space, but for
now this is a relatively simple approach that works on all platforms and
interops well with all applications.
