Implement the --build-id flag similarly to ELF, and generate a build_id section according to the WebAssembly tool convention specified in WebAssembly/tool-conventions#183 The default style ("fast" aka "tree") hashes the contents of the output and (unlike ELF) generates a v5 UUID based on the hash (using a random namespace). It also supports generating a random v4 UUID, a sha1 hash, and a user-specified string (as ELF does). Differential Revision: https://reviews.llvm.org/D107662
