[llvm] [RISCV] Include RISCVGenSearchTable.inc in RISCVISelDAGToDAG.h (PR #126326)

[Min-Yih Hsu via llvm-commits]

https://github.com/mshockwave created https://github.com/llvm/llvm-project/pull/126326

This line was previously removed when 12d47247e5046b959af180e12f648c54e2c5e863 moved it to RISCVInstrInfo.h. But we probably don't want to have dangling `#define *_DECL` (RISCVGenSearchableTables.inc will `#undef` these macros) and I think there is no harm putting declarations of those search table functions in RISCVISelDAGToDAG.h.
