Properties: Read xorg properties for all platforms

This CL updates all platform properties files to read the current xorg
configuration properties instead of setting them manually inside
the properties files.
Some overrides are required, to keep tests passing. Updating all
properties to the latest versions from xorg does break tests. I
suggest to carefully look into the properties that are still
manually defined and decide which of these are necessary, and which
indicate an actual broken test. For now this CL will only preserve
the current behavior without changing any score.

BUG=chromium-os:38031
TEST=touchtests run all
Same results as before.
