[TYPO3-core] RFC #15047 Remove trailing whitespaces in front of EOL

[Steffen Kamper]

Hi,

sry - this was for #15045

Committed #15047 to trunk rev 8145

As there are many extbase/fluid files involved, could you extract these 
and send to the forge project(s)? Otherwise these changes will get lost 
with next sync. Same with DBAL
