Until now, Genode's framebuffer session interface was based on the RGB565 pixel format. This patch changes the pixel format to 32-bit XRGB where the X part is ignored. It adapts all graphical applications and device drivers accordingly. The patch also adjusts the users of the drivers_interactive packages, assigning 64 MiB RAM and 1500 caps to the drivers subsystem, which is sufficient for covering high resolutions at 32 bits per pixel and to accommodate multi-component USB HID input stacks. Fixes #3784
