Add and use functions and macros for printing verbose testing output.
If the Memblock simulator was compiled with VERBOSE=1:
- prefix_push(): appends the given string to a prefix string that will be
printed in test_fail() and test_pass*().
- prefix_pop(): removes the last prefix from the prefix string.
- prefix_reset(): clears the prefix string.
- test_fail(): prints a message after a test fails containing the test
number of the failing test and the prefix.
- test_pass(): prints a message after a test passes containing its test
number and the prefix.
- test_print(): prints the given formatted output string.
- test_pass_pop(): runs test_pass() followed by prefix_pop().
- PREFIX_PUSH(): runs prefix_push(__func__).
If the Memblock simulator was not compiled with VERBOSE=1, these
functions/macros do nothing.
Add the assert wrapper macros ASSERT_EQ(), ASSERT_NE(), and ASSERT_LT().
If the assert condition fails, these macros call test_fail() before
executing assert().

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.

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.

Memblock simulator needs to be able to reset memblock data structures
between different test cases. Add a function that sets all fields to
their default values.
Add a test checking if memblock is being initialized to expected values.
