Add support for Android make

This change adds support for building TIM-VX under a
Android AOSP environment.

Instructions below based on Khadas VIMS system

* Add TIM-VX git repository to Android AOSP

  # cd vendor/amlogic/common/npu
  # git clone [email protected]:VeriSilicon/TIM-VX.git tim-vx

* Include tim-vx/Android.mk to AOSP build

  Edit vendor/amlogic/common/npu/Android.mak

    +TMP_PATH := $(LOCAL_PATH)
    +VIVANTE_SDK_DIR := $(LOCAL_PATH)/service/ovx_inc
    +include $(LOCAL_PATH)/tim-vx/Android.mk
    +LOCAL_PATH := $(TMP_PATH)

    ifeq ($(BOARD_NPU_SERVICE_ENABLE), true)

  Note VIVANTE_SDK_DIR needs to point to SDK header
  inclusion path
