[usage-statistics] Move logic related to anonymous usage statistics to separate package

[web-padawan]

Describe your motivation

The current version of the statistics checker has been implemented around 2018 and it has some issues.
In particular, the fact that this code relies on executing JS from the comment using eval() is just weird.

Now when we support modern browsers with import.meta we could consider re-implementing it.

Describe the solution you'd like

1. Create a new @vaadin/usage-statistics package in the web components monorepo for 24.1,
2. Re-implement the actual logic using import.meta if possible, e.g. using Vite as an inspiration,
3. Make sure only stats are collected and sent as described, and everything works as expected,
4. Consider also adding UsageStatisticsMixin instead of the ElementMixin for transparency.

Note, the usage statistics package is included in @vaadin/bundles which is built with Webpack. Webpack doesn't fully support import.meta by default, see webpack/webpack#15833. If somebody uses this package in an app based on Webpack, it won't work. It can probably be worked around by setting up DefinePlugin but that requires manual configuration.
