Userland: Change static const variables to static constexpr

Browse source 
`static const` variables can be computed and initialized at run-time
during initialization or the first time a function is called. Change
them to `static constexpr` to ensure they are computed at
compile-time.

This allows some removal of `strlen` because the length of the
`StringView` can be used which is pre-computed at compile-time.
