Read Package on demand and cache it (#2548)
This patch dramatically increases the efficiency of `juvix dev root`,
which was unnecessarily parsing all dependencies included in the
`Package.juvix` file. Other commands that do not require the `Package`
will also be faster.

It also refactors some functions so that the `TaggedLock` effect is run
globally.

I've added `singletons-base` as a dependency so we can have `++` on the
type level. We've tried to define a type family ourselves but inference
was not working properly.
