🐛[RUMF-1544] Fix badly polyfilled URL

[amortemousque]

Motivation

It has been observed that on some customer website, URL is badly polyfilled. It might not be a constructor, and might not provide a URL.createObjectURL function.

Changes

• Replace checkURLSupported by getSupportedURL to keep the original URL ref to avoid the URL is not a constructor error in the buildUrl.
• Check if URL.createObjectURL is supported for the recorder to avoid URL.createObjectURL is not a function error in the worker
• Add an ESLint rule to force using buildURL instead of new URL. Inspired by no-new-symbol rule

Testing

• Local
• Staging
• Unit
• End to end
