faab8f76 - [RISCV] Add th.ext(u) to RISCVDAGToDAGISel::hasAllNBitUsers. (#157133)

[RISCV] Add th.ext(u) to RISCVDAGToDAGISel::hasAllNBitUsers. (#157133) These instructions are being used by the scalar efficiency SIG to determine if we should have a standard instruction. Improving our support for these instructions may give better data for their analysis. I'll follow up by adding this to RISCVOptWInstrs too which will remove the 'w' suffixes added here.
