Description
Implement support of HiDPI splash screen loading on Linux.

The following methods from splashscreen_impl.h need to be implemented (see JDK-8043869):
void SplashSetScaleFactor(float);
char* SplashGetScaledImageName(const char*, const char*, float*); 

Some useful steps:
- get scale factor from the system (may be GDK_SCALE)
- it should be decided, which name conventions should be used for high-resolution splash images.
Comments
This change caused the build to break on Windows: JDK-8151770. The review changed makefiles but did not post on build-dev. I have several issues with the makefile changes that were made in this change. Please always post makefile/configure script changes to build-dev so that we may ensure the build stays functioning and well behaved.
