25c62dd0ef refactor(tvix/eval): introduce UpvalueCarrier trait
This trait abstracts over the commonalities of upvalue handling
between closures and thunks.

It allows the VM to simplify the code used for setting up upvalues,
without duplicating between the two different types.

Note that this does not yet refactor the VM code to optimally make use
of this.

e1147b57c7 feat(tvix/eval): introduce mechanism for defining builtins
Adds a new builtins module in which builtins can be constructed. The
functions in this module should return a correctly structured value to
be passed to the compiler's `globals`.

This is wired up all the way to the compiler with an example
`toString` builtin, available as a global. Note that this does not yet
actually behave like the real toString, which has some differences
from `Display`.

57d0dbb1c6 feat(tvix/eval): implement optional runtime tracing
This adds a `disassembler` feature to the crate configuration that
traces the operations executed and the state of the stack at runtime.

This can be enabled by compiling with `--feature disassembler`.

This will also gain a more sensible layout of code slices eventually.

7e77972d71 feat(tvix/eval): add mechanism for emitting warnings from compiler
These can be used predominantly to emit warnings about things that the
compiler can infer, such as deprecated language features.

f648cec78e feat(tvix/eval): Expose interpret + related types from lib
Add a new `lib.rs` to tvix/eval, which `pub use`s the `interpret`
function, and all types mentioned in its return type, and then uses
*this* instead of direct `mod` statements in the `main.rs` to implement
the entrypoints to the interpreter. This is in preparation for calling
these functions from integrated benchmarking infrastructure using
Criterion, though other things (like integration tests) might want to do
that as well.
