layout: support tiled gradients

Use background-size, background-position properties to render
CSS gradients.

Some cleanup in display_list_builder.rs related to gradient
calculations.

Adds two wpt tests for tiled gradients.

Note: For now even gradients with background-repeat: no-repeat
are repeated. Sometimes the gradient is not repeated everywhere.

Enable vars-background-shorthand-001.html CSS test.
