Consolidate the general, platform-agnostic part of the main()/WinMain()
in static FCHost::main() function to avoid code duplication.

Linux handlers and main() were copied from the cefsimple test app,
persistent storage implementation rewritten using cstdio and
std::filesystem to make it cross-platform.

Hack a Javascript color picker into FC when it's loaded from FCHost, since we don't have a native one.

Current versions of CEF no longer support CefFrame::LoadString, so switch to a data-URI scheme instead
