AVR: Add bitreverseqi2 insns.

Now that https://gcc.gnu.org/r17-591 has been applied, the
middle-end will express 8-bit bitreverse code in terms of
a 16-bit bitreverse.  Therefore, add bitreverseqi2 insns.

PR target/50481

* config/avr/avr.md (bitreverseqi2): New insn-and-split.
(*bitreverseqi2): New insn.
