Subject: [PATCH] Add debug for invalid GameProfiles on skull blocks/items

Improves the error message for placed in world skull blocks by default,
also adds 'Paper.debugInvalidSkullProfiles' system property which can be
set to 'true' for extra debug info (trace of updateGameprofile caller).

https://github.com/PaperMC/Paper/issues/7983 No longer functions as of 1.19
