[TASK] Deprecate BackendUtility::getTcaFieldConfiguration

The method getTcaFieldConfiguration is the first
to fall in BackendUtility as we now have a new
API for accessing information from TCA.

The last pieces have been migrated.

Historical fun fact: This method was introduced
with TYPO3 4.x to add support for IRRE in Workspaces
in 2010 by ohader:
"Add feature #16374: Implement Inline Relational Record Editing (IRRE) in Workspaces"

Kudos for this tremendous effort.
