Don't enable @viewport support in inspector emulation.

Don't enable @viewport support in inspector emulation.

Author support for @viewport is not enabled on Android and should not be
enabled in mobile emulation mode in the inspector. The idea is that if
@viewport support is enabled by default, it will be enabled on all
platforms, and there will be no need for a switch in the emulation code
of the inspector.

The only way of testing this, as @viewport is "experimental" and enabled for
testing, is to add a virtual "stable" test-suite for it. I thought that was a
bit overkill.

I have checked that the http://www.virtualsheetmusic.com looks as expected in
inspector emulation mode.

Hmm... When I added this originally, I was pretty sure that css viewport was
enabled for android. Either that changed, or I was mistaken.

Does this mean that layout test with @viewport is rendered differently in the
stable Chrome? Sounds scary.
