LOG: [clang] Replace PointerUnion::dyn_cast with llvm::dyn_cast (NFC) (#231373)

PointerUnion::dyn_cast has been soft-deprecated in favor of
llvm::dyn_cast and llvm::dyn_cast_if_present.  This patch replaces the
former with llvm::dyn_cast where the operand is guaranteed to be
nonnull.

ClassTemplateSpecializationDecl::getSpecializedTemplateOrPartial()
always returns a nonnull pointer by construction regardless of whether
the specialization is from a primary template or a partial
specialization.
