libstdc++: Optimize std::to_address

We can use if-constexpr and variable templates to simplify and optimize
std::to_address. This should compile faster (and run faster for -O0)
than dispatching to the pre-C++20 std::__to_address overloads.

libstdc++-v3/ChangeLog:

* include/bits/ptr_traits.h (to_address): Optimize.
* testsuite/20_util/to_address/1_neg.cc: Adjust dg-error text.
