Replace built-in Profiler with indicators in status bar

Now based on std::chrono, and also works in terms of emulated time
instead of frames, so we can in the future frame-limit even when the
display is disabled, etc.

The frame limiter can also be enabled along with v-sync now, which
should be useful for those with displays running at more than 60 Hz.

More ergonomic to use and will be required for upcoming changes.

They're not very important and this makes the display changes less
often, making it less distracting.

macOS uses bsdtar which doesn't have the -a flag which determines
compression based on file extension.
