Remove integrity attribute from elements not in SRI spec

Remove integrity attribute from elements not in SRI spec

Initially, it was anticipated that Subresource Integrity would cover
many more elements than the current version of the spec covers. While
many elements may be added in a future version of the spec, this CL
removes them since they are unspec'd and unimplemented.

Hi Philip. This removes the integrity attribute from the elements not in the SRI
spec, as discussed on blink-dev. Can you take a look? Thanks!

LGTM, but you'll have to update some expectations in LayoutTests/webexposed/ and
LayoutTests/virtual/stable/webexposed/ too.
