Add ART boot image profile to the ART APEX.

We will need the profile when we generate the primary boot image on
device.

Bug: 203492478
Test: Run `banchan com.android.art x86_64 && m` and see
  `$ANDROID_PRODUCT_OUT/apex/com.android.art/etc/boot-image.prof`.
Test: Run `lunch aosp_cf_x86_64_phone-userdebug && m` and see both
  `$ANDROID_PRODUCT_OUT/apex/com.android.art/etc/boot-image.prof` and
  `$ANDROID_PRODUCT_OUT/system/etc/boot-image.prof`, in different
  sizes.
Test: Start Cuttlefish with the built image and see both
  `/apex/com.android.art/etc/boot-image.prof` and
  `/system/etc/boot-image.prof` on device.
