Use relative error threshold in Rotation Vector CV Crosscheck test

The Rotation Vector CV Crosscheck test uses pixels as a measure of
error for the test's accuracy. As a result, the distance at which the
test is performed from the pattern on the ground directly impacts the
result of the test. The test now calculates a dynamic error threshold
based on the current position of the device.

Test: Executed test on multiple devices and ensured it passed
Test: Distorted test pattern and ensured test failed
Test: Verified test fails when rotation vector is not accurate
