FAL processed files are deleted

Description
How to reproduce¶
- set `config.noScaleUp = 0` in TS
- add a magic image to RTE
- preview the page in FE
Result: Image broken
Root cause¶
Setting config.noScaleUp causes this line to be executed in typo3/sysext/frontend/Classes/Page/PageGenerator.php:88
$GLOBALS['TYPO3_CONF_VARS']['GFX']['im_noScaleUp'] = isset($GLOBALS['TSFE']->config['config']['noScaleUp'])
? '' . $GLOBALS['TSFE']->config['config']['noScaleUp']
: $GLOBALS['TYPO3_CONF_VARS']['GFX']['im_noScaleUp'];
This makes ['GFX']['im_noScaleUp'] a string, while in BE (when the preview image is generated in RTE) this is only loaded from install tool, where this is a boolean value.
This tiny difference has the effect that the calculated checksums used to determine whether a processed file already exists mismatch and the already generated processed file is deleted from disk.

Abandoned patch.
The issue is way more dramatic.
We have the situation that user experience will differ for BE and FE, if GFX|im_noScaleUp does not match config.noScaleUp.
BE and FE would behave differently.
- Priority changed from Should have to Must have
- Target version set to next-patchlevel
#56147 deals with the issue that processed files are not regenerated. This is related here, since with this bug you can trigger the other bug easily.
Actually, if #56147 would be working, I would have never noticed this bug here.
Regarding this issue: We decided to remove the [GFX] part from the checksum and add a cleanup-util to the Install Tool.
- Target version changed from next-patchlevel to 6.2.13
- Sprint Focus set to Stabilization Sprint
I figured out the whole process now.
- After inserting the magic file into RTE
- a ProcessedFile is generated for the thumb
- When calling FE, it tries to render the file but (due to the data type issue) a new thumb (with new filename) is generated (so a new ProcessedFile)
- Having the click-enlarge static template loaded of RTE, causes it to render the name of the original processed file (from
>cObj>parameters, which contains the parsed RTE content), which has been deleted by the last step, when the new processed file was generated.
- In FE it looks like the thumb-regeneration has failed, which is not true. Just the filename of the original thumb is used, which does not exist anymore.
Ultima ratio:
Fixing the configuration change issue (removing GFX from the checksum) fixes the issue. The remaining FAL handling is totally fine in this case.
Implementation steps are:
- Remove [GFX] from the checksum generated in \TYPO3\CMS\Core\Resource\Processing\AbstractGraphicalTask::getChecksumData()
- Add a cleanup utility to Install-Tool, which allows to remove all processed files (#67071)
