Implement referrer policy delivery via noreferrer link relation
According to https://w3c.github.io/webappsec-referrer-policy/#referrer-policy-delivery, there's `<a>`, `<link>` and `<area>` could apply this delivery method. This PR contains changes for `<a>` and `<link>` **but** not `<area>`, since HTMLAreaElement is barely implemented.
We should file another issue for it.

This updates webrender to include the webgl related changes
needed for this patch. There was an additional commit in
webrender before these landed, so also copy the shaders
for that change across. There is an interface change to
webrender push_image. For now, just pass zero, which is a
no-op to this function. A follow up commit will introduce
the servo specific changes to use this new interface.
layout: Disable the speculation of block formatting contexts' inline sizes if the block formatting contexts have negative margins.
The heuristics that determine how and whether floats flow into the
margins are not valid in that case.
Closes#13299.

Make font template data load fallible
Remove a TODO around dealing with a failed file operation.
Can we write an automated test for this? I don't really know what font template data is, but this failure seems to be fontconfig-specific...

Two things changed, on one hand, avoid a dumb if chain that could be more
idiomatically written with a match expression, and also avoiding use map() to
change state.
In general I'm pretty surprised for our lack of error reporting in this
critical code, but that's not the purpose of this PR.
