  [ORC] Link LLVMOrcShared against TargetParser

Mangler::fromTriple() calls Triple::computeDataLayout(), which lives in
LLVMTargetParser, but LLVMOrcShared only lists Support as a link
component.

This goes unnoticed in a static build: the component is an archive, so
the reference is not resolved until the final executable link, where
LLVMTargetParser is present anyway. With BUILD_SHARED_LIBS=ON each
component becomes a shared library linked with -Wl,-z,defs, and linking
LLVMOrcShared itself fails:

  ld.lld: error: undefined symbol:
    llvm::Triple::computeDataLayout[abi:cxx11](llvm::StringRef) const
  >>> referenced by Mangler.cpp:50
