Add prebuilts for perfetto_hprof dependencies.

These are static libs that communicates with Perfetto using serialised
protobufs over fd's and in shared memory. Even so, it is a stable ABI
(https://perfetto.dev/docs/design-docs/api-and-abi#tracing-protocol-abi).

Test: build/soong/scripts/build-aml-prebuilts.sh platform-mainline-sdk
  unzip the zip file in a master-art tree without external/perfetto
  and build com.android.art
