    x86/ept: force WB cache attributes for grant and foreign maps
    
    Force WB type for grants and foreign pages. Those are usually mapped
    over unpopulated physical ranges in the p2m, and those ranges would
    usually be UC in the MTRR state, which is unlikely to be the correct
    cache attribute. It's also cumbersome (or even impossible) for the
    guest to be setting the MTRR type for all those mappings as WB, as
    MTRR ranges are finite.
    
    Note that this is not an issue on AMD because WB cache attribute is
    already set on grants and foreign mappings in the p2m and MTRR types
    are ignored. Also on AMD Xen cannot force a cache attribute because of
    the lack of ignore PAT equivalent, so the behavior here slightly
    diverges between AMD and Intel (or EPT vs NPT/shadow).

    x86/mtrr: move epte_get_entry_emt to p2m-ept.c
    
    This is an EPT specific function, so it shouldn't live in the generic
    mtrr file. Such movement is also needed for future work that will
    require passing a p2m_type_t parameter to epte_get_entry_emt, and
    making that type visible to the mtrr users is cumbersome and
    unneeded.
    
    Moving epte_get_entry_emt out of mtrr.c requires making the helper to
    get the MTRR type of an address from the mtrr state public. While
    there rename the function to start with the mtrr prefix, like other
    mtrr related functions.
    
    While there fix some of the types of the function parameters.
    
    No functional change intended.
