Cleanups for building Windows resources

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

Here are the details:
The naming of variables used for customizing resource properties in the build system should be aligned between hotspot and JDK.
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.
