Emilio Cobos Álvarez 51758cfc9b Bug 1829189 - Make OnAttrSetButNotChanged and AfterSetAttr infallible. r=smaug
Same rg + sed shenanigans as the first patch.

There were two that could fail, both due to OOM:

 * HTMLInputElement::AfterSetAttr: If we fail (only in the type=range
   case) we end up with an old value without it being clamped by
   min/max/step.

 * HTMLBodyElement::AfterSetAttr: If we fail we won't peek up the
   DocShell's frame margins and styling could be incorrect.

That seems better than having to deal with broken states after we've
already set the attribute.

Depends on D176069
