[TASK] Deprecation: <link> syntax parsing in RteHtmlParser

Functionality regarding parsing / resolving <link> tags is marked
as deprecated as it does not need to be called anymore.

Additionally, adding and calling the hooks
$TYPO3_CONF_VARS['SC_OPTIONS']['t3lib/class.t3lib_parsehtml_proc.php']['modifyParams_LinksRte_PostProc']
$TYPO3_CONF_VARS['SC_OPTIONS']['t3lib/class.t3lib_parsehtml_proc.php']['modifyParams_LinksDb_PostProc']
will trigger deprecation errors.
