JDK 10 RFR of JDK-8193489: Add information about local variable type inference to SourceVersion.RELEASE_10

[joe darcy]

Hello,

The javadoc for the enum constants in javax.lang.model.SourceVersion 
have short informative descriptions of the languages changes in each 
release. The text for SourceVersion.RELEASE_10 should be updated to 
mention local variable type inference (var).

Please review the patch below which adds this text.

Thanks,

-Joe
