  Log Message:
  -----------
  [RISCV] Add partial validation of Z extension name to RISCVISAInfo::parseNormalizedArchString (#90895)

If 'z' is given as the complete extension name or with a digit after it,
it will crash in the extension map compare function. Check for these
cases and give an error.
