ENH: Add `check_namespace` option in testing utilities.

[prady0t]

Add the option to disable or enable namespace check for xp_test in the private test functions. They already have toggles for dtype, shape, and scaler.

sounds good! Should be relatively easy, just guard

array-api-extra/src/array_api_extra/_lib/_testing.py

Lines 60 to 61 in 5045afa

	actual_xp = array_namespace(actual) # Raises on scalars and lists
	desired_xp = array_namespace(desired)

behind a new parameter
