mb/google/slippy: Add a VBT for all variants
The vbt was extracted from the option rom found on stock images. The vbt.bin is the same across all variants. The VBT has a modified BDB block 43, the 'Backlight info block' such that the inverter type for the panel in use is set to 2 (BDB_BACKLIGHT_TYPE_PWM) instead of 0 (BDB_BACKLIGHT_TYPE_NONE). This only seems to matter on Windows, as without it changing the backlight duty cycle does not work.
