Make compile targets a subcommand instead of a flag (#2700)
# Changes
The main goal of this pr is to remove the `--target` flag for `juvix
compile` and use subcommands instead. The targets that are relevant to
normal users are found in `juvix compile --help`. Targets that are
relevant only to developers are found in `juvix dev compile --help`.

Below I list some of the changes in more detail.
## Compile targets for user-facing languages
- `juvix compile native`
- `juvix compile wasi`. I wasn't sure how to call this: `wasm`,
`wasm32-wasi`, etc. In the end I thought `wasi` was short and accurate,
but we can change it.
- `juvix compile vampir`
- `juvix compile anoma`
- `juvix compile cairo`
## *New* compile targets for internal languages
See `juvix dev compile --help`.

1. `dev compile core` has the same behaviour as `dev core
from-concrete`. The `dev core from-concrete` is redundant at the moment.
2. `dev compile tree` compiles to Tree and prints the InfoTable to the
output file wihout any additional checks.
3. `dev compile reg` compiles to Reg and prints the InfoTable to the
output file wihout any additional checks.
4. `dev compile asm` compiles to Asm and prints the InfoTable to the
output file wihout any additional checks.
5. 4. `dev compile casm` compiles to Asm and prints the Result to the
output file wihout any additional checks. TODO: should the Result be
printed or something else? At the moment the Result lacks a pretty
instance.
6. 
## Optional input file
1. The input file for commands that expect a .juvix file as input is now
optional. If the argument is ommited, he main file given in the
package.yaml will be used. This applies to the following commands:
   1. `juvix compile [native|wasi|geb|vampir|anoma|cairo]`
   8.  `juvix dev compile [core|reg|tree|casm|asm]`
   1. `juvix html`
   3. `juvix markdown`.
   4. `juvix dev internal [typecheck|pretty]`.
   5. `juvix dev [parse|scope]`
   7. `juvix compile [native|wasi|geb|vampir|anoma|cairo]`
   9. note that `juvix format` has not changed its behaviour.

## Refactor some C-like compiler flags
Both `juvix compile native` and `juvix compile wasi` support `--only-c`
(`-C`), `--only-preprocess` (`-E`), `--only-assemble` (`-S`). I propose
to deviate from the `gcc` style and instead use a flag with a single
argument:
- `--cstage [source|preprocess|assembly|exec(default)]`. I'm open to
suggestions. For now, I've kept the legacy flags but marked them as
deprecated in the help message.

## Remove code duplication
I've tried to reduce code duplication. This is sometimes in tension with
code readability so I've tried to find a good balance. I've tried to
make it so we don't have to jump to many different files to understand
what a single command is doing. I'm sure there is still room for
improvement.

## Other refactors
I've implemented other small refactors that I considered improved the
quality of the code.

## TODO/Future work
We should refactor commands (under `compile dev`) which still use
`module Commands.Extra.Compile` and remove it.
