Get rid of `mir::Const::from_ty_const`

This function is strange, because it turns valtrees into `mir::Const::Value`, but the rest of the const variants stay as type system consts.

All of the callsites except for one in `instsimplify` (array length simplification of `ptr_metadata` call) just go through the valtree arm of the function, so it's easier to just create a `mir::Const` directly for those.

For the instsimplify case, if we have a type system const we should *keep* having a type system const, rather than turning it into a `mir::Const::Value`; it doesn't really matter in practice, though, bc `usize` has no padding, but it feels more principled.
