scripts/doc-tests-cross-check: check for collisions

Create script for checking if keywords used in descriptions
have any collisions, as we want them to appear in only one field.
For example, 'reset' word is used now in two different fields
Functionality and Sub-category:

tests/intel/xe_exec_reset.c: * Functionality: reset
tests/device_reset.c: * Sub-category: Reset

With this it will help to spot such potential problems.
