Add a symbols_map tool that can extract an identifiying hash from and elf file or an r8 dictionary. The tool writes the hash to a textproto, and also supports a merge mode to combine textprotos into a output file for inclusion in the build artifacts. Bug: 218888599 Test: m dist Test: symbols_map_test.go Change-Id: Icd3ed6e5510e058c92d97c78759e7a4cfcdbb6ca
