memblock tests: Add simulation of physical memory
Allocation functions that return virtual addresses (with an exception
of _raw variant) clear the allocated memory after reserving it. This
requires valid memory ranges in memblock.memory.
Introduce memory_block variable to store memory that can be registered
with memblock data structure. Move assert.h and size.h includes to common.h
to share them between the test files.
