anv: add a new execution mode for secondary command buffers

Browse Source 
This change adds a call/return execution mode for secondary command
buffer rather than the existing copy into the primary batch mode.

v2: Rework convention to avoid burning an ALU register (Jason)

v3: Use anv_address_add() (Jason)

v4: Move command emissions to anv_batch_chain.c (Jason)

v5: Also move last MI_BBS emission in secondary command buffer to
    anv_batch_chain.c (Jason)

v6: Fix end secondary command buffer end (Jason)

v7: Refactor anv_batch_address() to remove additional emit functions
