[core & timecop] Locale loading Statistics

[confused-Techie]

This PR tracks and displays locale load times in timecop for both Pulsar's own locales, and each package's locales.

This adds two new variables:

• atom.localeLoadTime: A variable on the atom global, that says how many milliseconds it took to load Pulsar's own locales.
• <package>.loadTime:locales: A variable on every single package, that says how many milliseconds it took to load that package's locales.

The additions in timecop look like this:

And use all available standards and practices in timecop to make it's addition as seamless as possible. Let me know what you think!

I've removed the package locale loading from timecop due to requests on Discord. Now leaving the menu looking like so:

But I am still leaving the metrics within the packages metadata, in case we want to inspect it at a later time

Seems reasonably done to me, at a glance?

Thanks for the approval @DeeDeeG, in reality this is a rather simple PR to allow some monitoring of locales, just to ensure nothing gets too out of wack
