All memblock data structure fields are reset in one function. In some
test cases, it's preferred to reset memory region arrays without
modifying other values like allocation direction flag.
Extract two functions from reset_memblock, so it's possible to reset
different parts of memblock:
- reset_memblock_regions - reset region arrays and their counters
- reset_memblock_attributes - set other fields to their default values
Update checks in basic_api.c to use new definitions. Remove
reset_memblock call from memblock_initialization_check, so the true
initial values are tested.
