tests: Fix tests code and comments style This patch applies clang-format settings to most of tests files. Some files were fixed "by-hand" to exclude some lines, which whould be less readable after automatic style fixing. Moreover, some comments (mostly in tests/lib/edid-test.c) were adjusted to match coreboot coding style guidelines.

tests: Improve test output readability When running multiple tests, e.g. by using unit-tests target, it is hard to differentiate, which output comes from which file and/or configuration. This patch makes the output easier to analyze and understand by using new wrapper macro cb_run_group_tests(). This macro uses __TEST_NAME__ value (containing test path and Makefile test name) as a group name when calling cmocka group runner. Example: Test path: tests/lib/ Makefile test name: cbmem_stage_cache-test Test group array name: tests Result: tests/lib/cbmem_stage_cache-test(tests) Signed-off-by: Jakub Czapiga <jacz@semihalf.com> Change-Id: I4fd936d00d77cbe2637b857ba03b4a208428ea0d Reviewed-on: https://review.coreboot.org/c/coreboot/+/57144 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Paul Fagerburg <pfagerburg@chromium.org> Reviewed-by: Julius Werner <jwerner@chromium.org>
