keep just one shared reference to Skia shared GrContext This should make it easier to keep the reference without having to keep references all over the place, especially when the shared GrContext starts to be used also for GPU-backed surfaces elsewhere.

rework Skia setup Calls to SkiaHelper::isVCLSkiaEnabled() may be done from many places, even if LO uses a VCL plugin that doesn't use Skia, which leads to the Skia code not being prepared properly (and crashing/asserting). So make the SalInstance of those relevant VCL plugins call a setup function that is required for Skia actually getting enabled. Avoids crashes/asserts in the About dialog if the Skia UI checkbox is enabled but e.g. the KF5 VCL plugin is actually used.

add (Vulkan) blacklisting to Skia Currently there's nothing blacklisted, but this is the code. And there's not much point in blacklisting CPU-based raster Skia, so check only for Vulkan. Since this requires accessing Vulkan to get the driver info, this commit also reorganizes a bit getting a GrContext when there's no actual window, so that it's usable for the test.

make Skia Windows widget drawing use correct alpha (tdf#129074) The OpenGL code made the widget drawing use two variants drawn on black and on white, for reasons not explained in 3149cc341b1866d215110f0783227549a99b5920 (probably the Windows API doesn't handle alpha completely correctly or whatever). This means that getting the actual alpha requires a custom algorithm that needs to be implemented manually for Skia use.
