lib/igt_kms: Rework pipe properties to be more atomic, v7.

In the future I want to allow tests to commit more properties,
but for this to work I have to fix all properties to work better
with atomic commit. Instead of special casing each
property make a bitmask for all property changed flags, and try to
commit all properties.

This has been the most involved one, since legacy pipe commit still
handles a lot of the properties differently from the rest.

Changes since v1:
- Dump all changed properties on commit.
- Fix bug in igt_pipe_refresh().
Changes since v2:
- Set pipe ACTIVE property changed flag on init.
Changes since v3:
- Add a missing igt_pipe_refresh() to kms_atomic_interruptible.
Changes since v4:
- Perform error handling when setting custom crtc properties.
Changes since v5:
- Only attempt to commit changes properties.
Changes since v6:
- Clear OUT_FENCE_PTR on succesful commit.
