Cleanup: remove STR_String usage from GHOST

Tests: fix some tests passing even if there are Python errors

Blender was not configured to exit with non-zero return code on Python errors.
A bunch of tests worked around this but not all. This removes the need for such
workarounds.

Fix Python bundled module test error

We don't bundle cffi, rather the ffi library is used for ctypes. This test is
currently passing even when there are errors, that will be fixed next.

Tests: add physics tests cloth and softybody

This uses the same framework as automated modifier tests. It adds a physics
modifier, bakes and compares vertex coordinates on the end frame.

Strengthen modifiers test validation, from D7397.

Submitting on behalf of Jesse Y (deadpin).
In test harness for modifier testing, now run mesh validation
on output mesh. Also, fix printing so it interleaves properly.

Fix T75973: don't show raw Python errors to users for invalid shortcut paths

There are cases when a user can accidentally assign an operator to toggle an
invalid property to e.g. left click, which shows Python errors to the users.
Rather than throw an error and e.g. break 3D viewport selection for the user,
just print an error to the console.

The root cause of such bugs should be fixed as well, but a working Blender
is most important here.

Alembic: added NURBS surface support to the new exporter

Exporting NURBS as polymesh works fine. Exporting as Alembic NURBS patches
is spotty at best, just like the original exporter, so the new exporter
is at feature parity here.

Alembic: added Curve writing to new Alembic exporter

BLI: add Map.is_empty() method
