Speed up \Drupal\Core\Plugin\Context\ContextHandler::checkRequirements by adding a hasMatchingContexts method

Problem/Motivation

\Drupal\Core\Plugin\Context\ContextHandler::checkRequirements calls getMatchingRequirements which evaluates each context. But in ::checkRequirements we only need to know if one context matches.

Steps to reproduce

Proposed resolution

Add a ::hasRequirements method, that uses foreach and returns early instead of using array_filter.

Remaining tasks

User interface changes

API changes

Data model changes
