intel: Use 3DSTATE_BINDING_TABLE_POOL_ALLOC exclusively on Gfx11+

Browse Source 
On Icelake and later, we can use a new 3DSTATE_BINDING_TABLE_POOL_ALLOC
command to update the location of the binder (buffer containing binding
table entries), rather than having to move Surface State Base Address
via a STATE_BASE_ADDRESS command.  This has less stalling and also means
our surface addresses can remain relative to a fixed 4GB address range,
meaning we don't have to re-stream them any time the binder changes.
