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().

Update comments in memblock_free_*() functions to match the style used
in tests/alloc_*.c by rewording to make the expected outcome more apparent
and, if more than one memblock is involved, adding a visual of the
memory blocks.
If the comment has an extra column of spaces, remove the extra space at
the beginning of each line for consistency and to conform to Linux kernel
coding style.

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.

Add checks for removing a region from reserved memory in different
scenarios:
- The requested region matches one in the collection of reserved
memory regions
- The requested region does not exist in memblock.reserved
- The region overlaps with one of the entries: from the top (its
end address is bigger than the base of the existing region) or
from the bottom (its base address is smaller than the end address
of one of the regions)
- The region is within an already defined region

- The requested region does not exist in memblock.memory

address is bigger than the base of the existing region) or from the
bottom (its base address is smaller than the end address of one of

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.
