`Solve() of `llb.Scratch()` returns a `nil` reference. This causes
Pipelines with no operations to panic when interacted with, because of
`nil` pointer de-reference.
Mitigates #189 and #184

Maps were causing the same Pipeline to randomly produce slightly different LLB
on each run (because they are represented as an array in LLB, wheras
they're a map in CueLLB).
This forces every Cue field iteration (env, mount, etc) to be
predictable by using stable sorting.

- Solver: Encapsulates all access to Buildkit. Can solve plain LLB, invoke external frontends (for DockerBuild) and export (for ContainerPush)
- FS (now BuildkitFS) implements the standard Go 1.16 io/fs.FS interface and provides a read-only filesystem on top of a buildkit result. It can be used with built-ins such as fs.WalkDir (no need to have our own Walk functions anymore)
- Moved CueBuild into compiler.Build since it no longer depends on Buildkit. Instead it relies on the io/fs.FS interface, which is used both for the base config and the stdlib (go:embed also uses io/fs.FS). Overlaying base and the stdlib is now done by the same code.

- Remove unnecessary Fill() in Export()
- Change `set()` and the way we store outputs so we don't fill
intermediaries as much
- WIP: Scan the tree only once. Changed LocalDirs to use cueflow rather than
doing our own Walk. In a follow up we should use the same flow
instance.

Now using the same pattern as Go's http package.
- the `compiler.Compiler` struct can be used directly (and tests to do
to avoid messing with the global version)
- `compiler.DefaultCompiler` contains a public default Compiler instance
- `compiler` exposes proxy functions (e.g. Compile) back to the
DefaultCompiler

This PR embeds the stdlib into the dagger binary itself for convenience.
Long term we will want to source the stdlib directly from git.
- Updated go to 1.16 to use the new built-in embedding functionality
- The `stdlib` go package now contains an embed of the stdlib

- Standard library is hosted at github.com/blocklayerhq/dagger-stdlib
- When dagger repo is made public, stdlib can be hosted from same repo
- Vendored cue.mod is merged with stdlib at file granularity
- When developing dagger, set DAGGER_DEV_STDLIB to a local stdlib
directory
