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

Merge branch 'master' into sculpt-mode-features

simplify action builders

Changed Displaytype to Vertical List and Horizontal List

Cleanup: Remove . at the end of text

Cloth: better flip edges implementation

USD: Removed debug prints

No functional changes.

Merge remote-tracking branch 'origin/master' into sybren-usd

Merge branch 'master' into greasepencil-object

Cloth: fix updating active faces after fixing mesh in collapse edges

compute particle functions more centrally for events

Cloth: better handling of split_edges()

create particle function for force inputs more centrally

Fix T67593: Crash when making link for instance collection

use particle function for gravity force
