RFR (S): 8221880: Better customization for Windows RC properties FileDescription and ProductName

Hello Christoph,

Looking closer at what we are doing, we are actually overriding 
JDK_RC_PLATFORM_NAME as well, and there are a couple of direct 
references to that variable in our custom makefiles. So I will still 
need to update those if this goes in.

In OpenJDK builds, the current strings evaluate to "OpenJDK Platform" 
and for Oracle builds "Java(TM) Platform SE". It makes me curious as to 
what you need to modify the string to?
