Export Content Mus for Unit Testing

I am planning on adding unit tests to content/renderer/mus/

In order to link during component builds, I need to export some classes. This change adds CONTENT_EXPORT to some classes.

As the mus client lib is not a component, mus base classes are not being exposed.

Hi Ben,

Could you review this change? I'm exporting some classes in content/renderer so
that they can be used in unit testing of content/renderer/mus

This will allow me to reland https://codereview.chromium.org/1749323002/ which
contains the tests.

Thanks,
Jon
