Make the API functions noexcept

Only relevant for C++, but these functions can't throw as it's a C-based API.
Letting the compiler know that helps improve code generation. Extension
callbacks must also not let exceptions leave the callback, or else Bad Things
can happen.

The macro AL_DISABLE_NOEXCEPT may be defined before including the headers to
not mark functions as noexcept, but this should only be done if the caller
can't otherwise be fixed.
