Use StyleForLayoutObject for option to update stacking context properly.

We used OriginalStyleForLayoutObject which doesn't update animations or
stacking context. Hopefully a better fix for 813348.

Reland: Use StyleForLayoutObject for option to update stacking context.

We used OriginalStyleForLayoutObject which doesn't update animations or
stacking context.

This is a reland of [1] which was reverted because the added unit test
failed on Android because option elements do not create layout objects
with the platform's theme.
