kselftest/arm64: Add SME support to syscall ABI test For every possible combination of SVE and SME vector length verify that for each possible value of SVCR after a syscall we leave streaming mode and ZA is preserved. We don't need to take account of any streaming/non streaming SVE vector length changes in the assembler code since the store instructions will handle the vector length for us. We log if the system supports FA64 and only try to set FFR in streaming mode if it does.
