f352ce36 - [SPIR-V] Emit SPIR-V generator magic number and version (#87951)

[SPIR-V] Emit SPIR-V generator magic number and version (#87951) This patch: - Adds SPIR-V backend's registered generator magic number to the emitted binary. The magic number consists of the generator ID (43) and LLVM major version. - Adds SPIR-V version to the binary. - Allows reading the expected (maximum supported) SPIR-V version from the target triple. - Uses VersionTuple for representing versions throughout the backend's codebase. - Registers v1.6 for spirv32 and spirv64 triple.
