Audio, GL: make the extension lists constexpr. 

The Audio::Extension::extensions() and GL::Extension::extensions()
functions now return an ArrayView instead of a reference to std::vector.
Having a function-local static std::vector is the worst thing ever. Ugh.

- @ref Audio::Extension::extensions() and @ref GL::Extension::extensions()
now return a @ref Corrade::Containers::ArrayView instead of a reference to
@ref std::vector in order to reduce binary bloat and compile times
- Removed all aliases to @ref GL library functionality in the root namespace
(and root include path) which were deprecated in 2018.04 and everything
