[RISCV] Select signed bitfield extract for Xqcibm (#143536)
The Xqcibm Bit Manipulation extension has the `qc.ext` instruction that
can extract a subset of bits from the source register to the destination
register.
Unlike the corresponding instructions in `XTHeadbb` and `XAndesPerf`
which extract the bits between `Msb` and `Lsb`, the `qc.ext` instruction
extracts `width` bits from an offset that is determined by the `shamt`.
