This patch implements the binding table enable command which is also
used to allocate a binding table pool where where hardware-generated
binding table entries are flushed into. Each binding table offset in
the binding table pool is unique per each shader stage that are
enabled within a batch.
Also insert the required brw_tracked_state objects to enable
hw-generated binding tables in normal render path.
v2: - Use MOCS in binding table pool alloc for GEN8
- Fix spurious offset when allocating binding table pool entry
and start from zero instead.
v3: - Include GEN8 fix for spurious offset above.
v4: - Fixup wrong packet length in enable/disable hw-binding table
for GEN8 (Ville).
- Don't invoke HW-binding table disable command when we dont
have resource streamer (Chris).
v5: - Reorder the state cache invalidate flush so it happens in-between
enabling hw-generated binding tables and the previous sw-binding
table GPU state (Chris).
v6: - Do the same fix in v5 for gen7_disable_hw_binding_tables().
- Adhere to coding guidelines and make comments more informative.

It's been merged into brw_state_flags::brw for simplicity and
efficiency.

Skylake's 3DSTATE_DS packet has a few more fields; we don't support
domain shaders yet though.

Eric believes this to be wrong and unnecessary, as the command is
supposed to emit an implicit rectangle primitive. However, empirically
the pixel pipeline is completely unreliable without it. So for now, it
stays until someone comes up with a better solution.
We'll need to do better than this when we implement multisampling, HiZ,
or fast clears...but for now, this will do.

v2: Also disable 3DSTATE_WM_CHROMAKEY for safety.
