Stephan Bergmann 5e8479a38f Remove a std::remove_reference_t
...which is unnecessary (short of dubious explicit invocations like
`makePropertyValue<int const &>(i)`) as T can never be deduced to be a reference
type there.  And add some test code (that also tests the bit-field scenario
mentioned in the commit message of 23cded985b
"Specialize comphelper::makePropertyValue for arithmetic types").
