anv: handle failures when growing reloc lists

Growing the reloc list happens through calling anv_reloc_list_add() or
anv_reloc_list_append(). Make sure that we call these through helpers
that check the result and set the batch error status if needed.

v2:
  - Handling the crashes is not good enough, we need to keep track of
    the error, for that, keep track of the errors in the batch instead (Jason).
  - Make reloc list growth go through helpers so we can have a central
    place where we can do error tracking (Jason).

v3:
  - Callers that need the offset returned by anv_reloc_list_add() can
    compute it themselves since it is extracted from the inputs to the
    function, so change the function to return a VkResult, make
    anv_batch_emit_reloc() also return a VkResult and let their callers
    do the error management (Topi)

v4:
  - Let anv_batch_emit_reloc() return an uint64_t as it originally did,
    there is no real benefit in having it return a VkResult.
  - Do not add an is_aux parameter to add_surface_state_reloc(), instead
    do error checking for aux in add_image_view_relocs() separately.
