Remove validation starter from web starters

This commit removes the validation starter from the web and
webflux starters - we've reconsidered that choice since many were
not using this feature as part of their default web experience.

Thit commit also changes the default EL implementation for the
Jakarta implementation, aligning all servers on it and simplifying
dependency management (especially exclusions that were required
previously).

Closes gh-19550
