Merge branch 'bjorn/remove-hybrid-heap/OTP-10105' into maint

* bjorn/remove-hybrid-heap/OTP-10105:
  Remove stale code for hybrid heap and incremental GC
  Remove the hipe_bifs:show_message_area/0 BIF
  Remove support for erlang:system_info(global_heaps_size)
  Remove the erlang:garbage_collect_message_area/0 BIF
  Remove workarounds for hybrid and shared heaps in test suites
