fix: erase dependencies on let-bound fvars in internalizeCode (#9922) 
This PR changes `internalizeCode` to replace all substitutions with
non-param-bound fvars in `Expr`s (which are all types) with `lcAny`,
preserving the invariant that there are no such dependencies. The
violation of this invariant across files caused test failures in a
pending PR, but it is difficult to write a direct test for it. In the
future, we should probably change the LCNF checker to detect this.

This change also speeds up some compilation-heavy benchmarks much more
than I would've expected, which is a pleasant surprise. This indicates
we might get more speedups from reducing the amount of type information
we preserve in LCNF.

refactor: split the LCNF pass list into separate base/mono lists (#9816) 
This will make it easier to run the two phases in parallel.

chore: remove unused impure LCNF Phase (#8924) 
The `.impure` LCNF `Phase` is not currently used, but was intended for a
potential future where the current `IR` passes (which operate on a
highly impure representation) were rewritten to operate on LCNF instead.
For several reasons, I don't think this is very likely to happen, and
instead we are more likely to remove some of the unnecessary differences
between LCNF and IR while keeping them distinct.

fix: use Arg in LCNF FVarSubst rather than Expr (#8729) 
This PR changes LCNF's `FVarSubst` to use `Arg` rather than `Expr`. This
enforces the requirements on substitutions, which match the requirements
on `Arg`.

chore: use mutual inductives for data structures in the new compiler (#8332) 
This PR changes the types `AltCore`, `FunDeclCore` and `CasesCore` used
in the IRs of the new compiler into the mutual inductives `Alt`,
`FunDecl` and `Cases`.

c1b7accd12 refactor: LCNF local context 
The previous implementation had a few issues:
- Function (and join point) declarations were being inserted into two different hashmaps.
- `borrow` information was not available for parameters.
- No proper erase functions.

this kind of fine-grain tracking is not worth it.
