Keith Randall b888a6227f cmd/cgo: fix cgo bad typedefs
Two fixes:

1) Typedefs of the bad typedefs should also not be rewritten to the
   underlying type.  They shouldn't just be uintptr, though, they should
   retain the C naming structure.  For example, in C:

   typedef const __CFString * CFStringRef;
   typedef CFStringRef SecKeyAlgorithm;

   we want the Go:

   type _Ctype_CFStringRef uintptr
   type _Ctype_SecKeyAlgorithm = _Ctype_CFStringRef

2) We need more types than just function arguments/return values.
   At least we need types of global variables, so when we see a reference to:

   extern const SecKeyAlgorithm kSecKeyAlgorithmECDSASignatureDigestX962SHA1;

   we know that we need to investigate the type SecKeyAlgorithm.
   Might as well just find every typedef and check the badness of all of them.
   This requires looping until a fixed point of known types is reached.
   Usually it takes just 2 iterations, sometimes 3.

Fixes #24161
