[TabLayout] Support better break strategies for tab text.

Is your feature request related to a problem? Please describe.
I have a TabLayout with four items in fixed mode. This means that on some devices, the text of some items ends up being too long and therefore breaks on to a second line. Since the text is only a single word though, it has to break in the middle of a word. With the current behaviour it does so without adding a hyphen/dash and in weird places.

Describe the solution you'd like
I would like to be able to set the break strategy, similar to how it can be set for a TextView.

Describe alternatives you've considered
I have considered making the tabs have 1 line maximum to prevent the line breaks entirely, but as far as I could figure out, the maxLines value is hardcoded in this library and can't be changed from implementors of this library. I have also considered setting the mode to auto or scrollable, however both produce unwanted effects when there would be enough space (these issues are already covered by #650).

Additional context
In this screenshot you can see, that it sometimes puts just a single character on a new line.

No file or test is named. Start by locating TabLayout's fixed-mode tab text setup and its existing maxLines handling, then compare the desired configuration with TextView's break-strategy behavior. Done means fixed tabs can use a selectable break strategy and no longer split single-word labels at unsuitable points.
