    Add MAX/MIN PAGE_SIZE and PAGE_SHIFT definitions of m68k for jemalloc(3).

    Background:
    - All m68k ports have fixed PAGE_SIZE value in their kernels,
      but each port uses different PAGE_SIZE value (4096 or 8192)
      due to historical reasons.
    - Currently module(7) binaries are built per each port so
      all m68k kernel sources don't support run-time variable PAGE_SIZE.
    - MI <uvm/uvm_param.h> assumes that the port supports a variable
      PAGE_SIZE on module(7) builds if both MAX_PAGE_SIZE and MIN_PAGE_SIZE
      are defined and they have different values.
    - On the other hand, jemalloc(3) checks MAX_PAGE_SHIFT in
      src/external/bsd/jemalloc/include/jemalloc/internal/jemalloc_internal_defs.h
      for internal optimization.
    - m68k ports share userland binaries (especially pkgsrc binaries)
      among all ports, so we need to define MAX_PAGE_SHIFT as 13 to
      support m68k ports where PAGE_SIZE==8192.
      (though this would affect only if static binaries built on
       4k page hosts are executed on 8k page hosts)

    To solve these inconsistency on PAGE_SIZE definitions,
    we should have an independent PAGE_SIZE related definitions
    for userland, but it requires major reorganization.
    For now (especially for netbsd-9) we define MAX/MIN PAGE_SIZE and
    PAGE_SHIFT values in <m68k/vmparam.h> only in !defined(_KERNEL) case.

    Discussed on source-changes-d@ and tech-kern@ with christos@ and thorpej@:
     https://mail-index.netbsd.org/source-changes-d/2020/01/thread1.html#012035
     https://mail-index.netbsd.org/tech-kern/2020/01/thread1.html#025954

    Should be pulled up to netbsd-9.
