This defines the kcmdline_prop context for properties controlled by kcmdlinectrl, and defines a property called kcmdline.binder for switching between the Rust and C implementations of the Binder driver. It is intended that additional kcmdline properties introduced in the future would share the same kcmdline_prop context. Test: Verified that setprop/getprop work and that the value is loaded properly at boot Bug: 326222756 Change-Id: Iea362df98d729ee110b6058c6e5fa6b6ace03d8e
