Breaking: #63818 - Removed Static file edit functionality

See Issue #63818

Description

A special TCA configuration enabled RTE fields to write its content to sections within files. The configuration was done in defaultExtras array, static_write section and documented in TCA reference->AdditionalFeatures->SpecialConfigurationOptions.

This functionality has been removed without substitution.

Impact

Content of RTE fields can no longer be written to files.

Affected installations

In the unlikely case that this feature was used by anyone its usage can be located by searching for static_write keyword in TCA configuration.

Migration

Move this logic elsewhere, eg. use hooks in DataHandler to write out DB content.
