Support compilation of Anoma transactions in nockma backend (#2693)
When we first implemented the Nockma backend we wrongly assumed that the
only entry point for Juvix compiled Nockma modules would be the main
function. Using this assumption we could add a setup step in the main
function that put the Anoma stdlib and compiled functions from the Juvix
module in a static place in the Nockma subject. References to the Anoma
stdlib and functions in the module could then be resolved statically.

However, one of the use cases for Juvix -> Nockma compilation is for
Anoma to run logic functions that are fields of a transaction. So the
user writes a Juvix program with main function that returns a
transaction. The result of the main function is passed to Anoma. When
Anoma calls the logic function on a field of the transaction, the setup
part of the main function is not run so the subject is not in the
required state. In fact, the logic function is not even callable by
Anoma because non-main functions in the Juvix module use a calling
convention that assumes the subject has a particular shape.

This PR solves the problem by making all functions in the Juvix module
use the Anoma calling convention. We make all compiled closures
(including, for example, the logic functions stored on resources in a
transaction) self contained, i.e they contain the functions library and
anoma standard library.

Modules that contain many closures produce large nockma output files
which slows down the evaluator. This will need to be fixed in the future
either with Nockma compression ([jam
serialization](https://developers.urbit.org/reference/hoon/stdlib/2p))
or otherwise. But it does not block the compilation and execution of
Anoma transactions.

Other fixes / additions:

* Extra tracing. You can now annotate output cells with a tag that will
be displayed in the output
* Unittests for listToTuple, appendRights helper functions
* Fixes for the nockma parser when parsing 'pretty nockma', specifically
stdlib calls, tags and functions_library atom.
* Adds `juvix dev nock run` command that can run a program output with
the `anoma` target.
* Remove the `nockma` target. As described above we always use the Anoma
calling convention so there's no need for a separate target for the
'juvix calling convention'
* Adds a `--profile` flag to `juvix dev nock run` which outputs a count
of Nockma ops used in the evaluation
* In tests we no longer serialise the compiled program to force full
evaluation of the compiled code. We added a negative test to check that
strings are not allowed in Nockma/Anoma programs,

it is output in a file `OUTPUT.profile` and has the following form:

```
quote : 15077
apply : 0
isCell : 0
suc : 0
= : 4517
if : 5086
seq : 5086
push : 0
call : 4896
replace : 1
hint : 8
scry : 0
trace : 0
```
