Drop counterproductive top-level const

...that was apparently left by accident by
24c709655e5c1ca51c6c6da7ef0cb733354f6d20 "clang-tidy modernize-pass-by-value in
comphelper", thwarting the use of std::move here.

And clean up the declarations in the include file, too.

(I came across this code with an upcoming loplugin:constmove that flags
suspicious uses of std::move involving const-qualified types.)
