[a11y] Add a semantics role for slider - #193324

Relands flutter#184029
Reverts flutter#193288

I reverted flutter#193288 because I was
told this PR was causing errors in g3 and i might need a g3 fix , but
then I reverted it and realized it didn't , It's just Github and G3's
source code being out-of-sync. now i'm trying to reland the same PR
