MDEV-26195: Use a 32-bit data type for some tablespace fields

Browse source 
In the InnoDB data files, we allocate 32 bits for tablespace identifiers
and page numbers as well as tablespace flags. But, in main memory
data structures we allocate 32 or 64 bits, depending on the register
width of the processor. Let us always use 32-bit fields to eliminate
a mismatch and reduce the memory footprint on 64-bit systems.
