Fix memory corruption in sculpt neighbors code

* Boundary info is no longer initialized with
SCULPT_boundary_info_ensure, instead PBVH_BMESH keeps
track of boundary vert flags internally. This prevents
nasty first-click lag on the smooth brush as well as anything
with autosmooth.

* Fixed SCULPT_dynamic_topology_sync_layers to properly sync
active/render/clone/mask layers indices.
* Fixed sculpt color bugs in pbvh drawing for bmesh.

Splines: Add bounding box node support

Splines: Cleanup: Remove another unecessary change

USD Import: remove mesh modifier duplicate code.

Refactored the mesh sequence cache modifier logic
to reduce duplication in the code paths for the USD
and Alembic formats.

Add transform option to disable cursor wrapping.

Transform operator had cursor wrapping categorically enabled, but this
gets quite confusing with the edge scrolling mechanism. A new TransInfo
option T_NO_CURSOR_WRAP has been introduced to disable this behavior.
The double negative is a bit annoying, but want to avoid affecting the
existing transform modes, so by default it should still set the
OP_IS_MODAL_GRAB_CURSOR flag (which then sets the WM_CURSOR_WRAP_XY
flag during modal execution).

EEVEE: Use C++ vector types

BLI: Add more operator to float2/3 and int2/3

Splines: Halve the size of the bezier interpolation cache

Use floats to store the control point indices and the interpolation factors.

BLI: add int2 and int3 C++ support

Simple addition based on float2/3.
