Main benefits of NetLog inner classes extraction:
- Greater code organization.
- Promotion of files being "include-what-you-use" clean. Less files now need
  to include "net_log.h"; these files are no longer susceptible to having their
  includes hidden by the many inner includes of "net_log.h".
- All touched files are also now forward-clean re: NetLog,
  NetLogCaptureMode and the new, extracted classes.

Here is the new structuring:
  - NetLogSource (net_log_source.h/.cc)
  - NetLogEntry, NetLogEntryData (net_log_entry.h/.cc)
  - NetLogWithSource (net_log_with_source.h/.cc)

***Did not extract NetLog::ThreadSafeObserver into its own class since
   NetLog::ThreadSafeObserver and NetLog are interrelated enough to keep
   NetLog::ThreadSafeObserver as an inner class.

Further Notes:
1) On top of scripting, all files were checked manually, ensuring:
     - Forwards/including added only when appropriate. No extras added.
     - "net_log.h" include removals done correctly. No "net_log.h"-hiding
       to occur as a result of new changes.

2) Just as any .cc file will not do the include/forward if the paired .h file
   already has the include/forward, *_unittests.cc, *_browsertest.cc and
   *_test.cc files exhibit the same behavior when they have a paired .h file.

3) Override methods' types do not add to logic for inserting forwards, since it
   is guaranteed that the base class has the forward.
     - Saw this done in codebase several times, so making sure to
       follow the same rule.

4) A big change was the mass adjustment for the include-hiding of
   NetLogCaptureMode by net_log.h includes. Now the NetLogCaptureMode class is
   being properly forwarded/included in all files changed by the original
   NetLog inner classes extraction work.

5) Many NetLog/NetLogWithSource includes/forwards were added across codebase.
   All instances of files seeing their NetLog/NetLogWithSource include/forward
   being hidden by their own includes should now be gone. This is to promote
   greater flexibility in future changes upon the codebase.
