Also allow arbitrary capitalization of the modes.

Also make linker and optimizer non-mutable config as the mode is cached after using them for the first time.

Accidentally introduced in c655b028

Also move tests to the rewriting test file

* Add trusted publishing

* Don't persist credentials in pypi.yml

* Don't persist credentials

This is an insecure default on GitHub that increases the chances of credential leakage.

This can only be done when the output of infer_shape of the core_op depends only on the input shapes, and not their values.

This Op does not really fit the CAReduce API, as it requires an extra bit of information (number of elements in the axis) during the loop. A better solution will be a fused Elemwise+CAReduce
