[lldb][test][NFC] Add LLDB test for UBSan trap frame recognizer (#151231)

In #145967 Clang was taught to emit trap reasons on UBSan traps in debug
info using the same method as `__builtin_verbose_trap`. This patch adds
a test case to make sure that the existing "Verbose Trap StackFrame
Recognizer" recognizes the trap reason and sets the stop reason and
stack frame appropriately.
