[PATCH i-g-t] tools/xe_gpu_frequency: Add tool to set/get Intel GPU frequency for Xe

[Badrappan, Jeevaka]

Hi Kamil,

> Please consider improving already existing tool intel_gpu_frequency instead of copy-paste.

There were 2 solutions considered:
1. Add support for Xe driver to the existing intel_gpu_frequency
2. Separate tool that will build on intel_gpu_frequency but specific to Xe driver

2nd solution was chosen for the below reasons:
- sysfs frequency path for i915 and Xe is different.
- tile and gt needs to be taken into consideration.
- Might not be accepted due to readability because of device type checks, name based on device types, extending i915 tool to support Xe driver.

If the recommendation is to extend intel_gpu_frequency, can provide a patch that adds supports for Xe driver to existing intel_gpu_frequency tool. Please confirm.

Will address in next patch set.
