Convert "Eclipse Project for Common Annotations" into a specification project

[waynebeaton]

In order to prepare this project to engage in specification work, we need to convert it into a specification project as defined by the Eclipse Foundation Specification Process (EFSP). As part of this work, we will change the project name and the scope.

We'll use this issue to capture the work that needs to be done as part of this effort.
