[clang-tools-extra] Replace SmallSet with SmallPtrSet (NFC) (#154365)

This patch replaces SmallSet<T *, N> with SmallPtrSet<T *, N>.  Note
that SmallSet.h "redirects" SmallSet to SmallPtrSet for pointer
element types:

  template <typename PointeeType, unsigned N>
class SmallSet<PointeeType*, N> : public SmallPtrSet<PointeeType*, N>
{};

We only have 10 instances that rely on this "redirection", with more
than half of them under clang-tools-extra/.  Since the redirection
doesn't improve readability, this patch replaces SmallSet with
SmallPtrSet for pointer element types.

I'm planning to remove the redirection eventually.
