b41b86a907f653f79bab10d4c80b3a41d146c71b added a new textual header `clang/Lex/HLSLRootSignatureTokenKinds.def` but did not add it to `clang`'s module map. This causes build failure when building llvm with `-DLLVM_ENABLE_MODULES=ON`. This PR adds the new textual header to the module map and fixes the build break. 

Fixing rdar://145148093.
