[TASK] Remove CSS Styled Content option of image position items

The extension configuration option that disables the disabling of
the superfluous options on CType=image (like "Left of Text") is
removed in favor of always disabling these options, which is the default
anyway.

Integrators can still override this change in their own PageTSconfig.
