RAS: Add fault injection support
The ARMv8.4 RAS extensions introduce architectural support for software to inject faults into the system in order to test fault-handling software. This patch introduces the build option FAULT_HANDLING_SUPPORT to allow for lower ELs to use registers in the Standard Error Record to inject fault. The build option RAS_EXTENSIONS must also be enabled along with fault injection. This feature is intended for testing purposes only, and is advisable to keep disabled for production images.
