kms_atomic: Add subtest for testing zpos plane property

We use a 16-bit pixel buffer format for the overlay plane, as some older
HW might not be capable of driving a 32-bit pixel format.

Changes since v2:
- use 0 for igt_paint_color_alpha() alpha parameter, as ARGB1555 uses
just 1 bit for (of) alpha (Philipp Zabel)

Changes since v1:
- fix 'commitintg' with 'committing' (Philipp Zabel)
- replace RGB565 with ARGB1555 (Philipp Zabel)
- test plane if it supports the pixel format supplied (Philipp Zabel)
