Implement curved RSU structure for the three layers of vertex barrel trackers

[ShujieL]

Briefly, what does this PR introduce?

created a new vertex barrel geometry file vertex_barrel_curved.xml with a new geo plugin to support smooth cylindrical surface and build-in inactive areas.
This work is a follow-up of #759 which creates flat sensors and barrel with staves.

What kind of change does this PR introduce?

• [ x ] New feature (issue #__)
• Documentation update
• Other: __

Please check if this PR fulfills the following:

• Tests for the changes have been added

Does this PR introduce breaking changes? What changes might users need to make to their code?

Does this PR change default behavior?

The # of hits on vertex barrels will reduce by a few percent due to the inactive areas.
Didn't see a significant change in tracking efficiency. Performance study on going.

VertexBarrelEnvelope_length and VertexTrackingRegion_length are not used anywhere. Can we remove them from dump-parameter-table?

Also, not sure why we keep VertexCheck in the xml file.

Also, validate-material-map failed due to "Propagation reached the step count limit of 1000 (did 1000 steps)". I remember seeing this error many times in the past but they didn't interrupt the program, a material map would still be generated. Any idea on how to deal with this? @wdconinc

no time to look into it until next week (not even sure then)
