/** Allocate a binding table
*
* This function allocates a binding table. This is a bit more complicated
* than one would think due to a combination of Vulkan driver design and some
* unfortunate hardware restrictions.
*
* The 3DSTATE_BINDING_TABLE_POINTERS_* packets only have a 16-bit field for
* the binding table pointer which means that all binding tables need to live
* in the bottom 64k of surface state base address. The way the GL driver has
* classically dealt with this restriction is to emit all surface states
* on-the-fly into the batch and have a batch buffer smaller than 64k. This
* isn't really an option in Vulkan for a couple of reasons:
*
* 1) In Vulkan, we have growing (or chaining) batches so surface states have
* to live in their own buffer and we have to be able to re-emit
* STATE_BASE_ADDRESS as needed which requires a full pipeline stall. In
* order to avoid emitting STATE_BASE_ADDRESS any more often than needed
* (it's not that hard to hit 64k of just binding tables), we allocate
* surface state objects up-front when VkImageView is created. In order
* for this to work, surface state objects need to be allocated from a
* global buffer.
*
* 2) We tried to design the surface state system in such a way that it's
* already ready for bindless texturing. The way bindless texturing works
* on our hardware is that you have a big pool of surface state objects
* (with its own state base address) and the bindless handles are simply
* offsets into that pool. With the architecture we chose, we already
* have that pool and it's exactly the same pool that we use for regular
* surface states so we should already be ready for bindless.
*
* 3) For render targets, we need to be able to fill out the surface states
* later in vkBeginRenderPass so that we can assign clear colors
* correctly. One way to do this would be to just create the surface
* state data and then repeatedly copy it into the surface state BO every
* time we have to re-emit STATE_BASE_ADDRESS. While this works, it's
* rather annoying and just being able to allocate them up-front and
* re-use them for the entire render pass.
*
* While none of these are technically blockers for emitting state on the fly
* like we do in GL, the ability to have a single surface state pool is
* simplifies things greatly. Unfortunately, it comes at a cost...
*
* Because of the 64k limitation of 3DSTATE_BINDING_TABLE_POINTERS_*, we can't
* place the binding tables just anywhere in surface state base address.
* Because 64k isn't a whole lot of space, we can't simply restrict the
* surface state buffer to 64k, we have to be more clever. The solution we've
* chosen is to have a block pool with a maximum size of 2G that starts at
* zero and grows in both directions. All surface states are allocated from
* the top of the pool (positive offsets) and we allocate blocks (< 64k) of
* binding tables from the bottom of the pool (negative offsets). Every time
* we allocate a new binding table block, we set surface state base address to
* point to the bottom of the binding table block. This way all of the
* binding tables in the block are in the bottom 64k of surface state base
* address. When we fill out the binding table, we add the distance between
* the bottom of our binding table block and zero of the block pool to the
* surface state offsets so that they are correct relative to out new surface
* state base address at the bottom of the binding table block.
*
* \param[in] entries The number of surface state entries the binding
* table should be able to hold.
*
* \param[out] state_offset The offset surface surface state base address
* where the surface states live. This must be
* added to the surface state offset when it is
* written into the binding table entry.
*
* \return An anv_state representing the binding table
