RFR: 8140723: Remove source code conditionalized on JAVASE_EMBEDDED

[David Holmes]

The bug report for this is confidential but quite simply all of the 
little tweaks and knobs we added to the open build and source files to 
support the Java SE Embedded product no longer need to be there for JDK 
9. A lot of this has already been addressed in relation to other changes 
(eg. new hotspot build), but this cleans out the rest.

There are related JDK changes being handled in a separate review thread. 
If you like you can see them all:

Thanks,
