Any test failure prevents the other tests to be run, aborting the entire test loop. This behavior was introduced by commit
9494d53d ("tests/kms_cursor_crc: Convert tests to dynamic").
For instance, when running the cursor-offscreen-32x10 subtest using VKMS,
the execution is aborted instead of SKIP/FAIL, as in the following output:

$ ./tests/kms_cursor_crc --run-subtest cursor-offscreen-32x10
(kms_cursor_crc:7447) igt_fb-CRITICAL: Test assertion failure function igt_create_fb_with_bo_size, file ../lib/igt_fb.c:2078:
(kms_cursor_crc:7447) igt_fb-CRITICAL: Failed assertion: (__kms_addfb(fb->fd, fb->gem_handle, fb->width, fb->height, fb->drm_format, fb->modifier, fb->strides, fb->offsets, fb->num_planes, flags, &fb->fb_id)) == 0
(kms_cursor_crc:7447) igt_fb-CRITICAL: Last errno: 22, Invalid argument
Stack trace:
kms_cursor_crc: ../lib/igt_core.c:1667: igt_fail: Assertion `_igt_dynamic_tests_executed < 0 || dynamic_failed_one' failed.
Received signal SIGABRT.

The test was aborted after convertig tests to dynamic with cursor size 32*10 that because of the assertion in the `igt_create_fb_with_bo_size` when creating cursor in `create_cursor_fb`.

This happened because Within a igt_subtest_with_dynamic block, explicit failure (e.g. igt_assert) is not allowed,
only dynamic subsubtests themselves will produce test results.

The previous approach was running each test for all cursor sizes then move to the next test  so fix this issue
by running all tests for one cursor size one by one, and check if cursor size is
supported or not before running the test.

Fixes: 9494d53d ("tests/kms_cursor_crc: Convert tests to dynamic")
