Fix wrong return value causing OpenXR initialization to fail

Fix compile errors on windows and with bundled OpenXR SDK sources

Refactor GHOST_XrContext into class + interface

Makes GHOST_Xr much more consistent with the rest of GHOST. Basically I
added a GHOST_IXrContext interface which can be called by the GHOST
C-API. The internal GHOST_XrContext class implements this.
Outside of GHOST only the opaque GHOST_XrContextHandle is accessible.

Kept GHOST_Xr_intern.h and GHOST_Xr.cpp for now. I'll probably remove
them soon. There's not much reason for both of them to be there.

GPencil: Cleanup commet

Outliner: Rewrite walk select

Rather than basing walk select on active flags, use a new TSE_WALK
flag to navigate. Also cleaned up and simplified code.

GPencil: Remove extra parameters to Convert API

Scene can be removed using context. Also bmain can be removed too.

Outliner: Utils made outliner_find_active more general

Rather than only searching for active, now search for element with
matching flag.

Fixed profile orientation issue with 1 segment long bevel chains.

Simple fix: The first edgehalf visited had the wrong orientation.
