target/82931: Make a pattern more generic to match more bit-transfers.
There is already a pattern in avr.md that matches single-bit transfers
from one register to another one, but it only handled bit 0 of 8-bit
registers. This change makes that pattern more generic so it matches
more of similar single-bit transfers.

Handle any bit position and use mode QISI.
* config/avr/avr.cc (avr_rtx_costs_1) [IOR]: Return a cost
of 2 insns for bit-transfer of respective style.
