* chore: migrate from base::StringPiece to std::string_view in keyboard_util.cc * chore: migrate from base::StringPiece to std::string_view in error_thrower.cc * chore: migrate from base::StringPiece to std::string_view in electron_api_web_contents.cc * chore: migrate from base::StringPiece to std::string_view in gin_helper/dictionary.h * chore: migrate from base::StringPiece to std::string_view in electron_api_url_loader.cc * chore: phase out internal use of base:::StringPiece `base::StringPiece` is being phased out upstream. Its code has been removed upstream and it's just a typedef for `std::string_view`. They haven't removed the typedef yet, so this PR tries to get ahead of future breakage by migrating "internal" use (i.e. leaving alone the places where the `base::StringPiece` name is coming from an upstream method that we override).
