Fix interpolation on 2D manifold in a 3D space

Issue/feature addressed

For the 2-D manifold in 3-D space, only two coordinates are used to find the host element. This may cause misjudgement when the projected bounding boxes of different elements overlap. In this merge request to ensure the nearest element is found, the third coordinate is used to calculate the distance in 3D space.

In addition, a hard-coded tolerance 1E-5 is used as the maximum distance in FieldConvert interpolation. This may cause failure in find element because a CAD model usually has a geometry error about 1E-5.

Proposed solution

After obtaining the local coordinates from two global coordinates, the third global coordinate on one element is computed and compared with the provided global coordinate as the distance to the manifold.

A distance tolerance option is passed to the interpolation modules.

Implementation

A PhysEvaluate is added in the Geometry2D::v_GetLocCoords and the 3-D distance to the manifold is calculated.
