AVR: ad target/84211 - Split MOVW into MOVs in try_split_any.
When splitting multi-byte REG-REG moves in try_split_any(),
it's not clear whether propagating constants will turn
out as profitable. When MOVW is available, split into
REG-REG moves instead of a possible REG-CONST.

PR target/84211
* config/avr/avr-passes.cc (try_split_any) [SET, MOVW]: Prefer
reg=reg move over reg=const when splitting a reg=reg insn.
