Ability to define default convention for specific Property types

[ljacomet]

While working on Java toolchains, we encountered a scenario where having a default convention on a created property would make sense:
In the context of a java project, it would be great if any task that uses a JavaLauncher (the toolchain provided java reference) would see its instance with the java extension toolchain convention.
Right now the wiring happens per plugin / per task.

If one could register default convention mappings on the property factory, the above could be simplified and also implicit for plugin authors leveraging toolchains in Gradle.
