memblock tests: add labels to verbose output for generic alloc tests

Generic tests for memblock_alloc*() functions do not use separate
functions for testing top-down and bottom-up allocation directions.
Therefore, the function name that is displayed in the verbose testing
output does not include the allocation direction.

Add an additional prefix when running generic tests for
memblock_alloc*() functions that indicates which allocation direction is
set. The prefix will be displayed when the tests are run in verbose mode.

memblock tests: update zeroed memory check for memblock_alloc_* tests

Update the assert in memblock_alloc_try_nid() and memblock_alloc_from()
tests that checks whether the memory is cleared so that it checks the
entire chunk of allocated memory instead of just the first byte.

memblock tests: add verbose output to memblock tests

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().

memblock tests: Add memblock_alloc_from tests for bottom up

Add checks for memblock_alloc_from for bottom up allocation direction.
The tested scenarios are:
- Not enough space to allocate memory at the minimal address
- Minimal address parameter is smaller than the start address
of the available memory
- Minimal address parameter is too close to the end of the available
memory

Add test case wrappers to test both directions in the same context.

memblock tests: Add memblock_alloc_from tests for top down

Add checks for memblock_alloc_from for default allocation direction.
The tested scenarios are:
- Not enough space to allocate memory at the minimal address
- Minimal address parameter is smaller than the start address
of the available memory
- Minimal address is too close to the available memory

Add simple memblock_alloc_from test that can be used to test both
allocation directions (minimal address is aligned or misaligned).
