Support Velocity toolbox configurations from jar
Create an EmbeddedVelocityToolboxView which supports loading toolbox.xml files from the application classpath as well as the ServletContext. The VelocityAutoConfiguration class has been updated to use the new view. This change allows the `spring.velocity.toolbox-config-location` property to work with embedded servlet containers. Fixes gh-2912
