RFR: 8370637: [Windows] Crash if use Graphics after PrintJob.end [v2]

[Phil Race]

> Synchronize WPrinterJob calls which use the printDC to avoid crash in case of mis-use.
> The printerDC is released when the job ends. 
> It is zero-ed out in the handle in which it is stored
> The calls which expect it to be valid now all check for zero and return if it is zero.
> The calls are made synchronized as is the call to endDoc which zeroes it, so that they cannot have it zeroed out whilst using it.
> 
> The tests are the same as in the fix for JDK-8370141 which is also under review.
> Which ever is 2nd to be pushed will have to merge in the changes from the first
