Reduce size of record offsets

Details

    Description

      Now offsets have stack part and heap part which is used when stack part can not hold that big amount of fields in a table. `mem_heap_t` is used to very wide tables. And the idea is to replace this dichotomy with stack only wider array with optimized offset size: uint16_t instead of ulint.
