Remove 'Experimental' label from Core Build Makefile projects. (#805)

Removed the 'Experimental' label in project creation wizard for Core
Build Makefile projects. Seven years after the inception it's time to
remove it. Core Build Makefile is now in a usable state. The
'Experimental' label scares users away from it, making them fall back
to the old Managed Build Makefile projects.
