Bug 1823411 - Give all webrender's shader varyings an explicit precision. r=gfx-reviewers,lsalzman

Browse Source 
Mali profiling tools have shown we are frequently fragment bound, in
particular due to varying interpolation. To help mitigate this, we
should use mediump where possible. Currently most of our varyings are
implicitly highp by default. This patch reduces their precision to
mediump where possible. When varyings must remain highp for
correctness reasons, this is now stated explicitly.

As expected, this does cause a fair bit of reftest fuzziness on
Android devices. This patch also updates reftest expectations to
reflect this.
