bgfx: crt-geom and crt-geom-deluxe enhancements (#7766) ...

Added a "brightness boost" feature for the shadow mask that works by making the brightness ratio between bright and dark mask pixels closer to 1 for the brighter parts of the image.

Added clamping to zero so that underscanning produces a black border.

Added a "raster bloom" effect to crt-geom-deluxe that makes the image grow slightly when the average brightness of the screen is high, mimicking a common defect in CRTs.
