RFR: 8244417: support static build for Windows

[Joeri Sykora]

Adds support for building static libraries of the OpenJFX modules for the Windows platform. Building static libraries
is done by providing the gradle property `-PSTATIC_BUILD=true`.

Changes include:

- add static flags for the compiler and linker
- use `lib` for linking instead of `link`
- only build and include version.rc once (from GlassResources.rc)
- include library specific `JNI_OnLoad_xxx` methods
- functionality loaded via `DllMain` has been implemented at a different location
