With multilayered framebuffer we want to allocate enough tile state for
all layers involved, so te binner can handle layered rendering where
a geometry shader is used to redirect primitives to specific layers by
writing to gl_Layer.
However, we may also have layered framebuffers in cases where layered
rendering won't be used. Typically this will happen for meta copy/clear
operations, where we setup multilayered framebuffers but then we just
load and/or store the tile buffer without ever rendering a primitive,
let alone use a geometry shader to do layered rendering. In these cases
we can reduce the amount of tile state allocated to a sigle layer.
This patch allows us to specify if we should allocate tile state for all
layers when we start a new frame. We will take advantage of this in
later patches targetting the meta copy/clear code paths.
