tests: Add tests for per commit zwp_buffer_release_v1 behavior

Browse source 
Add tests to check that the zwp_buffer_release_v1 events are emitted per
surface commit.

To be able to test this we need to use a renderer that holds the buffer
until the next buffer is committed, hence we use the pixman renderer.

Changes in v7:
  - Remove references to obsolete noop-hold renderer.

Changes in v5:
  - Meson support.

Changes in v4:
  - Use the pixman renderer instead of the (now gone) noop-hold
    renderer.
