RFR (S): 8221979: Cleanups for building Windows resources

[Langer, Christoph]

Hi,

during work on JDK-8221880 I spotted some opportunity for cleanup in Windows resource files and their handling in the build.

The naming of variables used for customizing resource properties in the build system should be aligned between hotspot and JDK. This should be carefully reviewed by the build team (Erik). Maybe there are conflicts with some Oracle internal usage of variables...

Furthermore some minor stuff:
There are some indentation issues in the rc files.
src/jdk.accessibility/windows/native/common/AccessBridgeStatusWindow.RC uses RC in capital letters as suffix, which is different to all other .rc files used.

Bug: https://bugs.openjdk.java.net/browse/JDK-8221979
Webrev: http://cr.openjdk.java.net/~clanger/webrevs/8221979.0/

Thanks
Christoph
