fix: fix gn cpplint warnings (#14583)

* chore: fix cpplint 'include_what_you_use' warnings

Typically by including <memory>, <utility> etc.

* chore: fix 'static/global string constant' warning

Use C style strings instead of std::string.

Style guide forbids non-trivial static / global variables. https://google.github.io/styleguide/cppguide.html#Static_and_Global_Variables

* refactor: remove global string variables.

Fix 'global string variables are not permitted' linter warnings
by using the base::NoDestructor<> wrapper to make it explicit that
these variables are never destroyed.

The style guide's take on globals with nontrivial destructors:
