🛃 Allow multiple action buttons in custom tab toolbar

Add a non-public flag to the TOOLBAR_ITEMS bundle extra, indicating that
the item should be shown on the top toolbar even if it doesn't have the
TOOLBAR_ACTION_BUTTON_ID. For now this allows showing a maximum number
of 2 buttons in the toolbar; any additional items will go into the
bottom bar.

Also, clean up CustomTabActivityTest (replace anonymous classes with
lamdas, simplify exceptions, etc.).

I'd like to merge https://chrome-internal.googlesource.com/clank/internal/apps/+/9ec067102cde99a499dd7588ddf6547d7780d827 to the 66 branch. It's a very small change that only bumps a version number that is only sent to first-party clients of Custom Tabs, it has tests and has gone through a Canary release.

The NextAction date has arrived: 2018-03-07

Your change meets the bar and is auto-approved for M66. Please go ahead and merge the CL to branch 3359 manually. Please contact milestone owner if you have questions.
