RFR: JDK-8282464: Remove author tags from java.compiler

[Joe Darcy]

To align with current coding conventions, the @author tags in the java.compiler module should be removed. The tags have not been maintained and updated in many years. These tags date back to the addition of JSRs 199 and 269 in JDK 6.

The authors at the time for these files were generally some nonempty subset of Scott Seligman, Peter von der Ahé, Jon Gibbons, Scott Seligman, and myself. The tag information will remain in the history of course.

I'll update the copyright years on the files before any push.
