This patch adds unit tests for verifying the sbi_ecall version,
impid handling, and extension registration functions. The tests
ensure that the extension registration and unregistration work
as expected.

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.

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.

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.
