feat: allow merging of leaves 
Consider the case of a MMR with one entry, and a new entry is being
added. Both of these values are quite unique, they are at the same time
the root and only leaf of their corresponding tree. Currently this
representation is not supported by the [MerkleStore], so the leaves are
not in it. Once the two values are merged, they both become leaves of a
new tree under the new parent, and the existing validation didn't permit
that promotion from happening.

This lifts the validation, and changes the method to clarify that not
only `root` are being merged, by arbitrary nodes of a tree (leafs,
internal, or roots), with arbitrary mixing of each.

feat: add MerkleStore::get_leaf_depth 
This commit introduces `get_leaf_depth`, a tiered SMT helpers that will
retrieve the depth of a leaf for a given root, capped by `64`.

feat: Add depth as store SMT argument 
Prior to this commit, MerkleStore allowed the creation of Sparse Merkle
tree only with the maximum depth of 63. However, this doesn't fit the
Tiered Sparse Merkle tree requirements, as it will contain trees of
depth 16.

This commit adds the `depth` argument to the MerkleStore methods that
will create Sparse Merkle trees.

bugfix: fix internal nodes of for empty leafs of a SMT 
The path returned by `EmptySubtreeRoots` starts at the root, and goes to
the leaf. The MerkleStore constructor assumed the other direction, so
the parent/child hashes were reversed.

This fixes the bug and adds a test.

feat: add empty subtree constants to cover u8::MAX depth 
Prior to this commit, we limited the constants count to 64 for the empty
subtrees depth computation. This is a hard-assumption that every tree of
Miden will have a depth up to 64 - and will cause undefined behavior if
it doesn't.

With the introduction of `MerkleStore::merge_roots` and the deprecation
of `mtree_cwm` instruction from the VM, this assumption is broken and
the user might end with trees with depth greater than 64. This broken
assumption could lead to attack vectors.

We can easily fix that by extending the pre-computed hashes list to the
maximum of `u8` (i.e. 255). This will have zero impact on functionality,
and will be completely safe to use without hard assumptions.
