feat(schema): to support borsh spec about sorted keys

[dzmitry-lahoda]

As per https://github.com/near/borsh?tab=readme-ov-file#specification:

all unordered containers (hashmap/hashset) are ordered in lexicographic order by key (in tie breaker case on value);

So HashMap and HashSet are ordered maps and sets.

In current schema I cannot distinguish that difference as part of schema enumeration, and has to resort to parsing rust types, which will not work for custom sorted things.
