Feature: #104054 - Add cache flush tags command 

Description 

A new command cache:flushtags has been introduced to allow flushing cache entries by tag.

Multiple tags can be flushed by passing a comma-separated list of tags. It is also possible to flush tags for a specific cache group by using the --groups or -g option. If no group is specified, all cache groups are considered.

Note that certain combinations of groups and tags do not make sense, specifically the di and system cache groups.

vendor/bin/typo3 cache:flushtags pageId_123
vendor/bin/typo3 cache:flushtags pages_100,pages_200
vendor/bin/typo3 cache:flushtags tx_news -g pages

Impact 

It is now possible to flush cache entries for specific tag and group combinations directly from the command line.
