anv: Better support for Android logging (v2)

anv: Better support for Android logging (v2)

In src/intel/vulkan/*, redirect all instances of printf, vk_error,
anv_loge, anv_debug, anv_finishme, anv_perf_warn, anv_assert, and their
many variants to the new intel_log functions. I believe I caught them
all.

The other subdirs of src/intel are left for a future exercise.

v2:
  - Rebase onto Tapani's VK_EXT_debug_report changes.
  - Drop unused #include <cutils/log.h>.
