CAMEL-20850: camel-core - compress changes in SimpleLRUCache

[essobedo]

Fix for https://issues.apache.org/jira/browse/CAMEL-20850 in Camel 4.0

Motivation

When the queue of changes is full, some entries can be evicted while the cache is not, which is not expected.

Modifications:

• Compress the changes by removing duplicates before the eviction
• Add a minimum size for the queue of changes
