This is a big step to split revng-lift in two parts: one that only writes the model and one that actually lifts to LLVM IR. * Introduce `revng import binary` * Split off `BinaryFile.h` * Drop `revng.h` * `GeneratedCodeBasicInfo`: use model * Reduce role of `GeneratedCodeBasicInfo` in favor of `model::Architecture` and `model::Register` methods * `CodeGenerator`: adopt `RawBinaryView` and model * `JumpTargetManager`: adopt `RawBinaryView` and model * `ExternalJumpsHandler`: adopt model * `InstructionTranslator`: discard `Architecture` in favor of `EndianessMismatch` * Many other changes
