    x86: don't offer Hyper-V option when "PV Shim Exclusive"
    
    This only added dead code. Use "if" instead of "depends on" to make
    (halfway) clear that other guest options should also go in the same
    block. Move the option down such that the shim related options get
    presented first, avoiding to ask the question when the answer may end
    up being discarded.
    
    While in the neighborhood also bring PV_SHIM_EXCLUSIVE into more
    "canonical" shape.
