0d93b01c - [RISCV] Don't crash if parseNormalizedArchString encounters a multi-letter extension with an unknown prefix. (#91398)

[RISCV] Don't crash if parseNormalizedArchString encounters a multi-letter extension with an unknown prefix. (#91398) The sorting code previously asserted if a prefix was multiple letters, but didn't start with s, x, or z. Replace the assert with an explicit check and sort the multi-letter extension after the known multi-letter prefixes.
