Use TryFrom<Vec<T>> impl for IndexVec

[Himess]

Closes #2532

I'm so sorry, this issue seems to have been closed in #2470! This added a TryFrom<Vec<T>> for IndexedVec<I, T> which is actually more appropriate considering the failure potential.

However, the challenge, now is to use it in the context in which this originally appeared, i.e. this should be used here:

miden-vm/core/src/mast/debuginfo/mod.rs

Lines 129 to 132 in 889140f

	let mut node_indptr_for_op_idx = IndexVec::new();
	for _ in 0..=num_nodes {
	let _ = node_indptr_for_op_idx.push(0);
	}

Not a problem at all @huitseeker, I've updated the PR as you suggested
