editors/lazarus*: Include new lazarus ports into mk files

• Add WANT_LAZARUS_DEVEL option if you want built apps using lazarus trunk version from ports. This variable can be added to /etc/make.conf. Otherwise, stable version of lazarus will be used.
• WANT_LAZARUS_DEVEL will use editors/lazarus-devel or editors/lazarus-qt5-devel ports instead of editors/lazarus or lazarus-qt5 ones
