Media: Revert WebP generation.

Given [https://make.wordpress.org/core/2022/09/11/webp-in-core-for-6-1/ Matt's recent post about removing WebP from core] and possibly implementing the feature in a future [https://make.wordpress.org/core/2022/09/11/canonical-plugins-revisited/ "Canonical Plugin"], this change reverts changesets [54086], [54094], and [54097].  Additionally, [54210] contained a coding standards follow-up in one of the affected files that is no longer needed.

Reverts [54086], [54094], and [54097].

Props SergeyBiryukov.
