[PATCH] lib:tests: enhance test output with colored pass/fail messages

[zhangdongdong at eswincomputing.com]

From: Dongdong Zhang <zhangdongdong at eswincomputing.com>

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.
