Remove EXPECT_DEATH

[elfenpiff]

Required information

In our cases using EXPECT_DEATH come often with undefined behavior which is unacceptable for certified tests. Possible approaches are:

• Create thread and call pthread_exit inside the error handler, would require the implementation of that feature in POSIX wrapper for pthreads #1365
• Throw an exception in the error handler, would require heavy refactoring and feature Only use noexcept in functions that definitely cannot throw #1392
• Another nifty idea.

ToDo

• (high prio) Define an alternative technique to EXPECT_DEATH and document it in the iceoryx testing document
• (high prio) Remove all occurrences of EXPECT_DEATH in cxx tests
• (medium prio) Remove all occurrences of EXPECT_DEATH in remaining hoofs
• (low prio) Remove all occurrences of EXPECT_DEATH in the remaining iceoryx repo
  • Using EXPECT_FATAL_FAILURE in combination with the RouDiEnvironment results in triggering the leak sanitizer
  • The same is the case when the SUT allocate in the call which leads to the fatal failure, e.g. the ctor of FileReader

Can be split up in further issues when required.

@elfenpiff last week @MatthiasKillat tried the approach with returning from a running thread. This might be the solution to remove the EXPECT_DEATH once the error handler is merged.
