With the introduction of KUnit, IGT is no longer the only option to run
the DRM unit tests, as the tests can be run through kunit-tool or on
real hardware with CONFIG_KUNIT.
Therefore, remove the "igt_" prefix from the tests and replace it with
the "drm_test_" prefix, making the tests' names independent from the tool
used.

The igt_check_drm_framebuffer_create is based on a loop that executes
tests for all createbuffer_tests test cases. This could be better
represented by parameterized tests, provided by KUnit.
So, convert the igt_check_drm_framebuffer_create into parameterized tests.

While we have multiple test cases, most of them check multiple
conditions, calling the function that is tested multiple times with
different arguments (with comments that indicate test case boundary).
This usually means that it can be easily converted into multiple test
cases.

The igt_check_drm_format_min_pitch() function had a lot of
KUNIT_EXPECT_* calls, all of which ended up allocating and initializing
various test assertion structures on the stack.
This behavior was producing -Wframe-larger-than warnings on PowerPC, i386,
and MIPS architectures, such as:
drivers/gpu/drm/tests/drm_format_test.c: In function 'igt_check_drm_format_min_pitch':
drivers/gpu/drm/tests/drm_format_test.c:271:1: error: the frame size of
3712 bytes is larger than 2048 bytes
So, the igt_check_drm_format_min_pitch() test case was split into three
smaller functions: one testing single plane formats, one testing
multi-planar formats, and the other testing tiled formats.
