Use "Test" instead of "Unit Testcases" to make string shorter.
Use uppercase to make it look more eye-catching.

Also,
- Rename UTEST_SMP_CALL_FUNC to RT_UTEST_SMP_CALL_FUNC.
- Add depends on RT_USING_SMP in Kconfig for RT_UTEST_SMP_CALL_FUNC
- Follow the naming rules of utest case to update the cases' name.

smp_call.h defines SMP-related structures and declares
SMP-related functions. These codes are only valid when
RT_USING_SMP is defined in the bsp, which means we have
to use RT_USING_SMP for judgment in every place where
this file is included, such as following:
```c
```
Now move the judgment of RT_USING_SMP directly into
smp_call.h, so that it's simpler to include the header
file as:
```c
```
