This allows the compiler to generate significantly better code, because
it does not have to maintain either the loop counter or loop limit. Plus
there are half as many symbols to relocate. This also simplifies passing
carray arrays to helper functions.

This patch introduces a new math test suite to the SBI unit
tests. The changes include:
* Updating lib/sbi/tests/objects.mk to include
math_test_suite and sbi_math_test.o.
* Adding a new file lib/sbi/tests/sbi_math_test.c which
contains tests for log2roundup function using various cases.
The addition of this test suite ensures that mathematical
functions are verified and work as expected.

This patch improves the readability of the SBI unit test
output by adding color-coded status messages.
Adding ANSI color codes for green (pass) and red (fail)
in sbi_unit_test.c.
Now, the test results will be displayed in green for passed
tests and red for failed tests, making it easier to quickly
distinguish between them.

We would like to clean any files generated by the carray
scripts by just searching for the filename as the current
make system turns f.carray into f.o. Change to make the
make system turn f.carray into f.carray.o
note, command to go through .mk files changing the .o
in the .mk files is:
find . -type f -name "*.carray" | xargs -t -I fname /bin/bash -x -c ' fn=`basename -s .carray fname`; echo "$fn"; sed -i `dirname fname `/objects.mk -e s/"$fn".o/"$fn".carray.o/g'

Implement the test which covers some of the functions from the
`riscv_locks.h` file. This test consists of 3 test cases:
1) For lock/unlock functions
2) Unsuccessful trylock (the lock was previously taken)
3) Successful trylock (the lock is free and can be taken)

Implement the test which covers some of the functions from the
`riscv_atomic.h` header file. The test contains 9 test cases:
1) atomic read/write test
2) add/return test
3) sub/return test
4) cmpxchg test
5) atomic_xchg test
6) atomic_raw_set_bit test
7) atomic_raw_clear_bit test
8) atomic_set_bit test
9) atomic_clear_bit test
Some of the test cases operate on the `test_atomic` variable. It gets
initialized in the suite init function.

Allow to define an init function for the test suite. It could help us
to initialize global variable once, and use them in multiple test cases
after the initialization.
For instance, if multiple test cases use the same atomic_t var, it
could be helpful to call ATOMIC_INIT once during the suite
initialization.

Move all of the SBIUnit-related code into the lib/sbi/tests directory.
Update 'Makefile' to index objects from the tests subdirectory.
I don't think creating the full separate list of Makefile variables
(libsbitests-objs-path-y, libsbitests-object-mks, etc. as it is done for
libsbiutils) is necessary for the tests because:
1) `lib/sbi/tests/objects.mk` is already indexed into
'libsbi-objects-mks' since the find expression for the libsbi-object-mks
variable looks for objects.mk files in the nested directories as well).
2) Tests are tightly coupled with the `lib/sbi/` sources, therefore it
may be reasonable to store the list of lib/sbi and lib/sbi/tests object
files together in the libsbi-objs-path-y variable.
Additionally, update relative paths in the tests where necessary.
