[TASK] Deprecate EidUtility and methods within TSFE

EidUtility is a poor-mans middleware functionality with
lots of side-effects, and is marked as deprecated.

On top, the following methods in
TypoScriptFrontendController are deprecated:
- initFEuser()
- storeSessionData()
- previewInfo()
- hook_eofe()
- addTempContentHttpHeaders()
- sendCacheHeaders()

Additionally, the PreviewInfo Hook
$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['tslib/class.tslib_fe.php']['hook_previewInfo']
is deprecated, as the eofe hook solves the same issues.

Resolves: #85878
