Physics overlap queries are not consistent when used against convex Mesh Colliders with a very small scale



Reproduction steps:
1. Open the attached 'ComputePenetrationTesting' project
2. Open the 'SampleScene'
3. Enter the Play mode
4. Observe the Console, note that collision is detected
5. While in Play mode, in the Scene View move the movingTestObject slightly inside the staticTestObject
6. Observe the Console

Expected result: the collision is always detected when the movingTestObject overlaps the staticTestObject
Actual result: the collision is not always detected when objects overlap

Reproducible with: 2019.4.34f1, 2020.3.25f1, 2021.2.7f1, 2022.1.0b2

    This bug is NOT totally fixed.

    It was combined with other bug and second part of it is still a bug.
    I've submitted it here:
    'New Incident created: IN-14809 - Physics overlap with convex Mesh __STILL__ don't work'
