Array API support - continuation

[mtsokol]

Hi @hameerabbasi,

This PR add a couple of simple Array API functions:

    "finfo",  # ported from numpy
    "iinfo",  # ported from numpy
    "isnan",  # the rest is just element-wise functions
    "isinf",
    "isfinite",
    "equal",
    "not_equal",
    "less",
    "less_equal",
    "greater",
    "greater_equal",
    "square",
    "logaddexp",
    "logical_and",
    "logical_or",
    "logical_xor",
    "trunc",

Adds __bool__, etc. to Tensor class.

It also introduces a few modifications to correctly run array-api-test suite.

---

The tricky part is reshape which we don't have right now but it's required by most of array-api-tests suites to even run them.
Maybe one option could be another env var TEST_MODE that when set enables temporary implementation (that moves to numpy, reshapes, and moves back to Tensor). Otherwise NotImplementedError is raised. WDYT?

We also need tests for everything here.

Looks good! Just a few tweaks to bitwise ops, the scalar changes, and the one change in full

The PR is ready from my side - I added tests and addressed all comments.

Let's just add a warning for the temporary reshape. Otherwise LGTM!
