[clang] [clang] Define SwiftInfo for RISCVTargetCodeGenInfo (PR #82152)

[Kuba Mracek via cfe-commits]

https://github.com/kubamracek created https://github.com/llvm/llvm-project/pull/82152

For Embedded Swift, let's unblock building for RISC-V boards (e.g. ESP32-C6). This isn't trying to add full RISC-V support to Swift / Embedded Swift, it's just fixing the immediate blocker (not having SwiftInfo defined blocks all compilations).
