since constructors can't actually be async we need a static wrapper
function that does the async work. it's fine, rust survives it too.

in the future eval states will be asyncio root contexts. proving that
they are used correctly is impossible if the are referenced by things
with weakly scoped lifetimes, or entirely unscoped lifetimes, as we'd
have to deal with in the case of `DrvInfos` passed as out parameters.

this will let us pass the capability to create debuggable eval errors
without having to pass an entire EvalState. we could pass symbols and
debug states around just as easily, but if we add new capabilities to
our debugger we might have to change many more places than with this.

not all of these are even used by eval itself. notably sWith wasn't used
at all, sEpsilon was only used by the eval cache one layer up, and other
attributes are used in places even further away from eval itself. we can
keep this commingling for now, but eventually we should clean it up too.

clangd broke because it can't look through symlinks. compile_commands
manipulation does not fix it, clangd configuration does not fix it, a
vfs overlay does not fix it, and while a combination of those can fix
it with a bind mount in place that's just too cursed to even consider
