Render boot animation with same size as framebuffer

When ro.surface_flinger.max_graphics_{width|height} is
set the framebuffer size is limited by this property.
However the boot animation size matches the display active
mode size which can cause it to be off-center or partially
visible.

This change limits the boot animation surface size with
accordance with ro.surface_flinger.max_graphics_width.
