Per their documentation, the `llvm::Initialize*` functions are only supposed to be called by the main program, not by a library like toolchain/codegen. Fixes a hang due to a data race in multithreaded autoupdate. Add a utility class `Carbon::InitLLVM` to do the common LLVM initialization shared by all Carbon tools, optionally including initializing the LLVM targets. Because the LLVM targets add a lot of binary size, only initialize them for binaries that opt in by depending on a new target `//common:all_llvm_targets`. Also fix `//explorer:file_test` and `//explorer:file_test.trace` to share a binary rather than linking an identical binary twice. --------- Co-authored-by: Jon Ross-Perkins <jperkins@google.com>
