This is part of a stack of PRs to add support for symbolizer markup in linux. Render contextual symbolizer markup elements. For Fuchsia it is not necessary to emit any context given that Fuchsia's logging infrastructure already handles emitting it when necessary. For more information about contextual symbolizer markup elements: https://llvm.org/docs/SymbolizerMarkupFormat.html#contextual-elements Reviewers: PiJoules, petrhosek, vitalybuka Reviewed By: petrhosek, vitalybuka Pull Request: https://github.com/llvm/llvm-project/pull/73194
