Ensure that an x_dim and y_dim exist, and are ordered as [..., y_dim, x_dim]. Cleans up function.
Is in preparation for optimising averaging.

* PI-2472: Area weighted regridding (#3623)

* The Area-weights routine is refactored into the "__prepare" and "__perform" structure, in-line with our other regridding methods.
* The area-weights are now computed in the "__prepare", so are calculated once.
* The information required for checking the regridding weights and target grid info are now cached on the "regridder" object.
* This is inline with the general use already described in the documentation.

* pep8 conformance.

* pep8 compliance.
