JDK 9 RFR of JDK-8172458: Make javax.lang.model javadoc HTML 5 compliant

[joe darcy]

Hello,

The javadoc in javax.lang.model.* and javax.annotation.processing use 
some constructs that are not HTML 5 compliant. These constructs should 
be updated to be compliant with HTML 5, mostly replacing <tt></tt> tags 
with <code></code>. Please review the proposed changes below:
