NEWT Soft-PixelScale (p6): Implement Soft-PixelScale for X11 and Windows ... (working state)

Both:
- Using Soft-PixelScale mode, i.e. converting all given window-units to pixel-units for native GDI/X11 ops
- Using scaled pixel-sized surface
- Adjusting NEWT's Monitor's window-unit viewport value to pixel-scale

For X11:
- Using global scale factor from environment variable, either: "GDK_SCALE", "QT_SCALE_FACTOR" or "SOFT_SCALE".
  The latter is for testing only.
  See https://wiki.archlinux.org/title/HiDPI

For Windows:
- Using actual monitor's pixel-scale via native SHC API (Shellscaling API, shcore.dll)

Misc:
- SurfaceScaleUtils.getGlobalPixelScaleEnv() reads a float value from given env names, first come, first serve
- MonitorModeProps.streamInMonitorDevice(..): Add `invscale_wuviewport` argument to scale wuvieport for soft-pixel-scale
- TestGearsNEWT: Enhance GL2 demo to be suitable for manual tests, this since my Windows KVM machine doesn't support ES2
- TestGLContextDrawableSwitch10NEWT: Add a few more test constraints .. working

Tested:
- Manually on a Windows virtual machine (KVM) using
  - 2 virtualized 'Video QXL' cards and
  - and 'remote-viewer' to see the 2 monitors
    since `Virtual Machine Manager` build-in doesn't support
    - remote-viewer spice://localhost:5917

- Manually on a Linux machine w/ SOFT_SCALE

- Both, X11 and Windows
  - Place window on each monitor
  - Move window across monitors w/ pixel-scale change (or not)

- TODO: Test and fix utilization with AWT, i.e. NewtCanvasAWT
