    [RISC-V] Add missing insn types to xiangshan.md and mips-p8700.md
    
    This is a trivial patch to add a few missing types to pipeline models that are
    mostly complete.
    
    In particular this adds the "ghost" to mips-p8700.md and the "sf_vc" and
    "sf_vc_se" types to xiangshan.md.
    
    There are definitely some bigger issues to solve in this space.  But this is a
    trivial fix that stands on its own.
    
    I've tested this in my tester, just waiting for pre-commit CI to do its thing.
    
    gcc/
            * config/riscv/mips-p8700.md: Add support for "ghost" insn types.
            * config/riscv/xiangshan.md: Add support for "sf_vc" and "sf_vc_se"
            insn types.
    
    (cherry picked from commit 00e1be7b34f8c009938dde2cf9ca4374243a7a9e)
