Remove legacy Xtensa port; leave README with pointer to latest partner-maintained code

Description

The Xtensa FreeRTOS port has been consolidated in the Partner-Supported submodules, along with numerous updates and bug-fixes.
The old location now contains a README indicating where to find the latest version of the Xtensa port and test code.

Test Steps

• Tested via various demo and stress tests as provided through the Partner-Supported-Demos submodule.
• Regression testing on many different LX7, LX8, and NX configurations.

Checklist:

• [ x ] I have tested my changes. No regression in existing tests.
• [ x ] I have modified and/or added unit-tests to cover the code changes in this Pull Request.

Submitting updated Xtensa port to FreeRTOS v11

I've created pull requests for Cadence's updated Xtensa FreeRTOS port and demo code. As you recommended, we have moved it to the Partner-Supported-Ports and Partner-Supported-Demos submodules, removed out-of-date code from the higher-level repos, and left a couple of READMEs in the old locations indicating the new home for this code.

Thank you in advance for your help reviewing this upstream request.

FreeRTOS/FreeRTOS-Kernel-Partner-Supported-Ports#15 has been merged. Could you move the submodule pointer?

Thanks, @aggarg. Rebased on top of main. Is it best to squash the 2 commits or to leave them separate?
