RFR: 8234335: Remove line break in class declaration in java.base

[Julia Boes]

Hi,

This cleanup work addresses an outdated coding convention in java.base. 
It removes the line break from a class declaration, for example:

     public
     TypeNameOnNextLine

becomes

     public TypeNameOnSameLine
