Introduce USES= pkgconfig to replace USE_PKGCONFIG

It can take 3 arguments:
build (default,implicit) to add pkgconf into BUILD_DEPENDS
run to add pkgconf into RUN_DEPENDS
both to add pkgconf into both RUN and BUILD DEPENDS

This deprecates USE_PKGCONFIG, please convert your ports.
USE_PKGCONFIG will be removed as soon as it is no more used in
the ports tree
