There were several error messages that appeared even if the hipEnvVarDriver.exe test passes and executes successfully. Now it is cleaned up. The following are those instances:
* When popen searches for directed_test directory but does not find it, it outputs an error, then finds the hipEnvVar at the same level. Currently the fix will prompt the test to only output an error if both searches for hipEnvVar fails.
* When assertion is used towards the later half of the test, conditions were set to specifically hide the devices, resulting in No Hip Device detected in the latter half of the test. The fix will make these errors not appear as they are intended to not find any devices. Assertions themselves are untouched.
HipEnvVarDriver.cpp has also been refactored. Reading HipEnvVar will now happen in a helper function for getDeviceNumber and getDevicePCIBusNumRemote, as the code to read HipEnvVar were really similar in them.
