CFE_SB_TimeStampMsg in ut_sb_stubs.c does not record MsgPtr argument value

[asgibson]

Describe the bug
The value passed into CFE_SB_TimeStampMsg cannot be checked because the context value is not put into the UT_Stub_CopyFromLocal function.

To Reproduce
Write a unit test that attempts to check this value by setting up UT_SetDataBuffer.
Test fails because the value was never saved so it will not equal the expected value.

Expected behavior
UT_SetDataBuffer when used for CFE_SB_TimeStampMsg will copy the argument value from local (UT_Stub_CopyFromLocal).

Code snips
Current code:

void CFE_SB_TimeStampMsg(CFE_SB_MsgPtr_t MsgPtr)
{
    UT_DEFAULT_IMPL(CFE_SB_TimeStampMsg);
}
