Random cleanups in c/b/enterprise_reporting.

- Don't alias namespaces in header files as per
  https://google.github.io/styleguide/cppguide.html#Namespaces
- A few iwyu cleanups.
- Use AddAllocated to pass an element's memory to a repeated proto
  field.
- Move a pair of funcs in BrowserReportGenerator into an unnamed
  namespace.
- Avoid copies when iterating over plugins in
  BrowserReportGenerator::OnPluginsReady.
