s390/mm: Add memory allocation profiling hooks

Similar to common code changes [1] add alloc_hook() wrappers to page table
allocation functions to allow for memory allocation profiling.

If CONFIG_MEM_ALLOC_PROFILING is enabled call sites of page table
allocations are accounted, instead of e.g. only crst_table_alloc() and
page_table_alloc(). This allows for slightly better profiling data, and the
output of /proc/allocinfo is similar to other architectures.

Without alloc_hook() wrappers the output of /proc/allocinfo looks like
this:

    17096704     4174 mm/memory.c:1061 func:folio_prealloc
    17809408     4348 mm/memory.c:1063 func:folio_prealloc
           0        0 mm/memory.c:4422 func:alloc_swap_folio
           0        0 mm/memory.c:4286 func:__alloc_swap_folio
           0        0 mm/memory.c:4971 func:alloc_anon_folio
         ...

           0        0 arch/s390/mm/pgalloc.c:124 func:page_table_alloc_pgste
     4280320     1045 arch/s390/mm/pgalloc.c:149 func:page_table_alloc

With alloc_hook() wrappers:
