  -----------
  [RISCV][GlobalISel] Fold large constant offsets in selectAddrRegImm (#219161)

Fold ADDI adjustment (AddiPair) for offsets in [-4096, 4094] and split
larger constants into materialized Hi + Lo12 offset, matching SDAG. Add
isWorthFoldingAdd to guard the split and extract the shared ADDI
renderer into renderAddiPair.
