fix: do not allow access to private primitives in public scope (#9890) 
This PR addresses a missing check in the module system where private
names that remain in the public environment map for technical reasons
(e.g. inductive constructors generated by the kernel and relied on by
the code generator) accidentally were accessible in the public scope.

perf: consider functions with ordinary implicit arguments of instance type to be template-like (#9536) 
This extends the specialization behavior of functions taking instance
implicits to ordinary implicit arguments that are of instance type. The
choice between the two is often made for subtle inference-related
reasons. It also affects visibility of these functions, because the
module system makes template-like decls visible to the compiler in other
modules.

perf: do not import non-template IR for codegen (#8666) 
This PR adjusts the experimental module system to not import the IR of
non-`meta` declarations. It does this by replacing such IR with opaque
foreign declarations on export and adjusting the new compiler
accordingly.

This PR should not be merged before the new compiler.

Based on #8664.

in the IRs of the new compiler into the mutual inductives `Alt`,
`FunDecl` and `Cases`.

fix: support borrowed params in the new compiler (#8127) 
This PR adds support for borrowed params in the new compiler, which
requires adding support for .mdata expressions to LCNF type handling.

feat: Array.insertIdx/eraseIdx take a tactic-provided proof (#6133) 
This PR replaces `Array.feraseIdx` and `Array.insertAt` with
`Array.eraseIdx` and `Array.insertIdx`, both of which take a `Nat`
argument and a tactic-provided proof that it is in bounds. We also have
`eraseIdxIfInBounds` and `insertIdxIfInBounds` which are noops if the
index is out of bounds. We also provide a `Fin` valued version of
`Array.findIdx?`. Together, these quite ergonomically improve the array
indexing safety at a number of places in the compiler/elaborator.

went from 31593 to 361.
