MDEV-33658 1/2 Refactoring: extract Key length initialization

Browse Source 
mysql_prepare_create_table: Extract a Key initialization part that
relates to length calculation and long unique index designation.

append_system_key_parts call also moves there.

Move this initialization before the duplicate elimination.

Extract WITHOUT OVERPLAPS check into a separate function. It had to be moved
earlier in the code to preserve the order of the error checks, as in the tests.
