tests/kms_plane: Run test for all supported pixel formats, v2.

This patch adds a subtest related to pixel format testing. The test
tries to create framebuffer with all supported pixel formats on every plane,
and tries to draw them using cairo and commits the same on display.

Changes since v1:
- Make the test more generic and try on all planes, including legacy cursor.
