[ESLint] Add a deprecation plugin to warn on deprecated code

[1Copenut]

Is your feature request related to a problem? Please describe.
We identified a legacy document method to copy text to the clipboard in #6912 and realized we don't currently lint for deprecated code.

Describe the solution you'd like
We would like to add ESLint-plugin-deprecation to warn (could also error) on deprecated code. It'd help us identify areas for improvement and keep EUI current with browsers.

The project has two dependencies, both of which are already in the EUI package.json file:

• @typescript-eslint/parser
• typescript

👋 Hi there - this issue hasn't had any activity in 6 months. If the EUI team has not explicitly expressed that this is something on our roadmap, it's unlikely that we'll pick this issue up. We would sincerely appreciate a PR/community contribution if this is something that matters to you! If not, and there is no further activity on this issue for another 6 months (i.e. it's stale for over a year), the issue will be auto-closed.

Hello! I would like to contribute with this issue. Actually I just made a PR (#8198 ) a couple of weeks ago, but I don't really know what is the process to expect a review. Thank you!
