Tune search order of path probes
Within the groups of user-provided and system-provided paths,
environment variables need to take precedence over properties, because
there is currently no other way to override the search paths of probes
from the outside if the probe-using code did not explicitly bind them to
Product/Module properties.
We search directly user-provided paths before ones from system-provided
environment variables to minimize the risk of surprises due to outside
influence.
[ChangeLog][Behavior Changes] The lookup order in PathProbe changed to
[environmentPaths, searchPaths, platformEnvironmentPaths,
platformSearchPaths]
