Subject: [PATCH] BLD, TST: Build and test Pyodide wheels for `pandas` in CI
 (#57896)

* Create initial Pyodide workflow

* Do not import pandas folder from the repo

* Install hypothesis for testing

* Add pytest decorator to skip tests on WASM

* Skip `time.tzset()` tests on WASM platforms

* Skip file system access tests on WASM

* Skip two more tzset test failures

* Skip two more FS failures on WASM

* Resolve last two tzset failures on WASM

* Add a `WASM` constant for Emscripten platform checks

* Fix floating point imprecision with `np.timedelta64`

* Mark tz OverflowError as xfail on WASM

* Try to fix OverflowError with date ranges

* Move job to unit tests workflow, withdraw env vars

* Fix up a few style errors, use WASM variable

* Bump Pyodide to `0.25.1`

See https://github.com/pyodide/pyodide/pull/4654 for
more discussion. This commit resolves a build error
coming from the `pyodide build` command which
broke due to a new `build` release by PyPA.

* Use shorter job name

* Skip test where warning is not raised properly

* Don't run `test_date_time` loc check on WASM

* Don't run additional loc checks in `test_sas7bdat`

* Disable WASM OverflowError

* Skip tests requiring fp exception support

* xfail tests that require stricter tolerances

* xfail test where `OverflowError`s are received

* Remove upper-pin from `pydantic`

* Better skip messages via `pytest.skipif` decorator

* Import `WASM` var via public API where possible

* Unpin `pytest` for Pyodide job

* Add reason attr when using boolean to skip test

* Don't xfail, skip tests that bring `OverflowError`s

* Skip timedelta test that runs well only on 64-bit

* Skip tests that use `np.timedelta64`
