MDEV-19526 heap number overflow on innodb_page_size=64k
InnoDB only reserves 13 bits for the heap number in the record header,
limiting the heap number to be at most 8191. But, when using
innodb_page_size=64k and secondary index records of 7 bytes each,
it is possible to exceed the maximum heap number.
btr_cur_optimistic_insert(): Let the operation fail if the
maximum number of records would be exceeded.
page_mem_alloc_heap(): Move to the same compilation unit with the
only caller, and let the operation fail if the maximum heap number
has been allocated already.
