gh-519: test array API compliance of legacy mode functions

[Saransh-cpp]

Description

Add array API tests for legacy mode functions added in glass.algorithm. The functions added in other modules do not fully support the array API standard; therefore, those functions can be dealt with once we add full support.

Closes: #519

Checks

• [X] Is your code passing linting?
• [X] Is your code passing tests?
• [X] Have you added additional tests (if required)?
• [ ] Have you modified/extended the documentation (if required)?
• [ ] Have you added a one-liner changelog entry above (if required)?

The typing and rng issues need to be worked out ideally before merging this. Hence, marking as draft.

Thanks @Saransh-cpp! What is the issue with array.reshape() here?

[Saransh-cpp]

Thanks, @ntessore! array.reshape() exists in JAX and NumPy but it is not a part of the array API (array_api_strict tests fail).

[Saransh-cpp]

This should finally be ready now, @paddyroddy @ntessore!

Merging this so that it does not go stale again!
