[Testing] Performance tests for 'store' collections.

[ruseinov]

This covers basic operations for store collections as well as comparison between Unordered* and Iterable* iteration performance.

This works fine on other platforms, but fails the osx CI.
Locally on OS X it works, but can be reproduced by limiting the thread amount: #[tokio::test(flavor = "multi_thread", worker_threads = 2)].
My guess is that the machine running mac os x tests just does not have enough CPU.

Potential fixes:

1. Remove parallelism - that'll result in very slow test runs.
2. Disable this on osx CI - it's enough to run those tests on linux.
3. Upgrade the macos GH runner: https://github.blog/2023-03-01-github-actions-introducing-faster-github-hosted-x64-macos-runners/

I have fixed this by removing parallelism on account creation. However, it takes under a minute on linux builds and about 10 mins on mac os x. So it might still be interesting to investigate upgrading the runners.
It takes about the same time locally on my mac too, a bit long.

Please, add a test for random access iteration which was the main motivation for these tests in the first place.

It is so much cleaner now! Great job

I will merge it now and will try to address near-workspaces-rs release sooner rather later. I hope it won't block publishing for near-sdk to crates.io

Thanks for great reviews!
