    docs: fmv:  Update Function multi-versioning documentation [PR c/122202]

    This updates the FMV documentation to the current state of things,
including
    the addition of "target_version" based FMV.

    Left as much of the x86 target based FMV documentation unchanged as
    the behaviour change there should be unchanged. Though highlights some of
    the differences between it and target_version FMV to try avoid confusion
there.
