feat: unify lower EL EA tests

Lower EL External Abort tests were implemented in such a way that after
triggering EA in tftf it gets trapped in EL3 and causing a crash in EL3
Because of the tests ending up in crash there are few problems:
 - Need to have to seperate tests one each for sync EA and Serror.
 - Unable to test the behaviour of system had the lower EL EA's been
   properly handled in EL3

This patch removes two separate configurations into a single test under
Firmware first handling(FFH). TF-A build macro PLATFORM_TEST_EA_FFH
allows fvp to have a proper handling.

This test configuration tests FFH(SCR_EL3.EA = 1) without RAS.

No need to create a new lower el panic test as they are tested in other
scenarios also.
