Feature: #65584 - Add image cropping

Description

A new functionality is introduced that allows the editor to define image cropping settings to a sys_file_reference.

The current support crop setting is a comma separated string defining: offsetX,offsetY,width,height

Impact

The value set for a sys_file_reference will be passed through to the image rendering of TYPO3 by default. The new option of sys_file_reference is defined as exclude field in TCA so it needs to be enabled for editors.

Disable cropping of image when used with typoscript rendering:

# Disable cropping for all images
tt_content.image.20.1.file.crop =

Set custom cropping setting for when used with typoscript rendering:

# Overrule/set cropping for all images
tt_content.image.20.1.file.crop = 50,50,100,100

Disable cropping of image when used in fluid:

<f:image image="{imageObject}" crop="" />

Set custom cropping setting for image when used in fluid:

<f:image image="{imageObject}" crop="50,50,100,100" />
