amdgpu/amd_abm: Fix getting and setting abm level property

This patch addresses a few problems:

1. Inner loop that iterates over the properties uses the same iterator
as the outer loop over connectors. If the eDP panel isn't on the first
output, then it won't be checked and the tests will skip.

2. We can get null pointer deferences if any of the DRM calls return
NULL.

3. The proplist isn't freed after being acquired.

These can be fixed by using the kmstest_get_property helper to
get the prop_id. The prop_id and KMS connector ID are then stored
for use later in the test when we need to set the ABM level.

All the necessary cached state has been placed into a data structure and
many callsites have been updated to make use of this.
