There are a couple of post-commit CI failures (#144022) after we made changes to the CPU definitions.

The reason is that RISCVTargetParserDef.inc does not get rebuilt when RISCVProcessors.td is modified, because the build rule for RISCVTargetParserDef.inc does not declare a dependency on RISCVProcessors.td, as shown in build.ninja.

The CMake version should be less than 3.23; otherwise, it will use depfiles (.inc.d) instead.

Should we explicitly add all the .td files under llvm/lib/Target/RISCV/ as dependencies of RISCVTargetParserDef.inc , similar to file(GLOB_RECURSE global_tds "${LLVM_MAIN_INCLUDE_DIR}/llvm/*.td")?
