Fix vertical list layout when thumnail view was active previously

Cloth: initial steps towards creating a mapping between BMVert* and ClothVertex for improving efficiency

added latest repo code

USD: Cleanup, removed unnecessary `struct` keyword

No functional changes.

USD: Export mesh normals

We now write face-varying mesh normals to USD. When the mesh has custom
loop normals those are written. Otherwise the poly flag `ME_SMOOTH` is
inspected to determine the normals.

This commits also changes the subdivision scheme from the default value
'Catmull Clark' to 'None', indicating we're exporting a polygonal mesh.
This is necessary for USD to understand our normals; otherwise the mesh
is always rendered smooth. In the future we may want to expose this
choice of subdivision scheme to the user, or auto-detect it when we
actually support exporting pre-subdivision meshes.

A possible optimisation could be to inspect whether all polygons are
smooth or flat, and mark the USD mesh as such. This can be added when
needed.

USD: Remove the "uv_" prefix from exported UV maps

The primvar name is now the same as the UV Map name. This is to allow
the standard name "st" for texture coordinates by naming the UV Map as
such, without having to guess which UV Map is the "standard" one.

Cloth: better handling of sizing

add utility to combine strings on the stack

USD: simplified nested condition in USDAbstractWriter::write()

By flipping a condition the code became much simpler.

No functional changes.

USD: replaced throwing temp C++ exception with BLI_assert() call

The exception was for making things easier to debug for me. Now the issues
are gracefully ignored when things go bad, which is better for users.

No functional changes.

simplify creating particle function

simplify action builders

Changed Displaytype to Vertical List and Horizontal List

Cleanup: Remove . at the end of text
