[V8] Prepare blink-downstream switch to swarming

This creates a new abstraction for determining ToT failures or failures
with --future flag. The shared code of these two methodologies is
shared now.

This also inlines a few constant configuration values and removes the
temporary timeout extension.

[V8] Switch blink-downstream to swarming

This switches BlinkTest to SwarmingIsolatedScriptTest. Since
blink_downstream doesn't implement any of the dynamic testing
configuration features of Chromium, we hard-code all required
configuration values.

We're close to declaring victory. The linux release builder is green again and looks like it works as it should. We can add it back to lkgr.

The debug builder is broken as it uses 'release' to find the builds on swarming. Needs investigation.

We also should use lower FYI prio for all bots but the lkgr one. We should also maybe use different shard numbers on different bots, like chromium does.
