We get consistent crashtest failures in CI when image.svg.blob-image
is set to true. This is because on some teardown paths, we don't verify
to see if the layer manager still owns the namespace used for the blob
keys.

WebRenderBridgeChild::GetFontKeyForScaledFont can currently cause a IpcResourceUpdateQueue race.
If we're in the middle of a transaction building a blob image, GetFontKeyForScaledFont is called
in the blob image building code using the transaction's IpcResourceUpdateQueue as expected, such
that resource updates are sent out when the transaction is finalized.
However, TextDrawTarget calls into PushGlyphs without passing along its IpcResourceUpdateQueue,
calling GetFontKeyForScaledFont without it, and causing it to immediately send out the resource
update.
So if a blob image uses a font key and submits a resource update, but a display list is built
after that also using the font key within the transaction, the display list will fail to send
the resource update because it thinks the blob image already did, even though the blob image
transaction has not yet been finalized.
The simple fix is to just pass IpcResourceUpdateQueue from TextDrawTarget into PushGlyphs, thus
ensuring the resource updates are properly ordered.

This WebRenderImageProvider/ISurfaceProvider subclass provides the
implementation for blob recordings. This is mostly just taking the
functionality that was previously in SourceSurfaceBlobImage.
