As part of the effort to remove the dependency that liferay-faces-util.jar has on the Liferay Portal API (FACES-2299), this sub-task involves deleting the com.liferay.faces.util.portal.WebKeys class from liferay-faces-util.jar and fixing any references to the String constants in any affected modules like liferay-faces-bridge-impl.jar and/or liferay-faces-portal.jar.

In older branches such as 3.2.x, 3.1.x, 3.0.x, 3.0.x-legacy, 2.2.x, and 2.1.x the string constants in WebKeys.java are to be deprecated. Rather than depending on portal-service.jar, the values of the string constants are to be replaced with literal values.
