kunit: Add test attributes API structure Add the basic structure of the test attribute API to KUnit, which can be used to save and access test associated data. Add attributes.c and attributes.h to hold associated structs and functions for the API. Create a struct that holds a variety of associated helper functions for each test attribute. These helper functions will be used to get the attribute value, convert the value to a string, and filter based on the value. This struct is flexible by design to allow for attributes of numerous types and contexts. Add a method to print test attributes in the format of "# [<test_name if not suite>.]<attribute_name>: <attribute_value>". Example for a suite: "# speed: slow" Example for a test case: "# test_case.speed: very_slow" Use this method to report attributes in the KTAP output (KTAP spec: https://docs.kernel.org/dev-tools/ktap.html) and _list_tests output when kernel's new kunit.action=list_attr option is used. Note this is derivative of the kunit.action=list option. In test.h, add fields and associated helper functions to test cases and suites to hold user-inputted test attributes.

kunit: Add ability to filter attributes Add filtering of test attributes. Users can filter tests using the module_param called "filter". Filters are imputed in the format: <attribute_name><operation><value> Example: kunit.filter="speed>slow" Operations include: >, <, >=, <=, !=, and =. These operations will act the same for attributes of the same type but may not between types. Note multiple filters can be inputted by separating them with a comma. Example: kunit.filter="speed=slow, module!=example" Since both suites and test cases can have attributes, there may be conflicts. The process of filtering follows these rules: - Filtering always operates at a per-test level. - If a test has an attribute set, then the test's value is filtered on. - Otherwise, the value falls back to the suite's value. - If neither are set, the attribute has a global "default" value, which is used. Filtered tests will not be run or show in output. The tests can instead be skipped using the configurable option "kunit.filter_action=skip". Note the default settings for running tests remains unfiltered. Finally, add "filter" methods for the speed and module attributes to parse and compare attribute values. Note this filtering functionality will be added to kunit.py in the next patch.
