Add $<CONFIG:...> boolean query generator expression

This expression evaluates to '1' or '0' to indicate whether the build
configuration for which the expression is evaluated matches tha named
configuration.  In combination with the "$<0:...>" and "$<1:...>"
expressions this allows per-configuration content to be generated.
