Replace deprecated base::NonThreadSafe in /content/browser/loader in favor of SequenceChecker.

Replace deprecated base::NonThreadSafe in /content/browser/loader in favor of SequenceChecker.

Note to crash team: This CL is a refactor and has no intended behavior change.

This change was scripted by https://crbug.com/676387#c84.

If you're wondering why there's a second wave of this, the first version of the
script handled "NON_EXPORTED_BASE(public base::NonThreadSafe)" but not
"public NON_EXPORTED_BASE(base::NonThreadSafe)"...

Note-worthy for the reviewer:
 * SequenceChecker enforces thread-safety but not thread-affinity!
   If the classes that were updated are thread-affine (use thread local
   storage or a third-party API that does) they should be migrated to
   ThreadChecker instead.
 * ~NonThreadSafe() used to implicitly check in its destructor
   ~Sequence/ThreadChecker() doesn't by design. To keep this CL a
   no-op, an explicit check was added to the destructor of migrated
   classes.
 * NonThreadSafe used to provide access to subclasses, as such
   the |sequence_checker_| member was made protected rather than
   private where necessary.

Hi, this is an automated change made by https://crbug.com/676387#c84 and sharded
across directories for OWNERS.

No human has looked at this specific output yet, see cl description for things
to watch for.

If it LGTY, please CQ.

Thanks!
Gab
