amdkfd: Bump ABI to indicate presence of Trap handler support for expert scheduling



commit 0f0c8a6983db ("drm/amdkfd: Trap handler support for expert
scheduling mode") introduced support for a trap handler when expert
scheduling mode. However userspace needs to know whether or not a trap
handler support is present.

Bump the KFD IOCTL API so that userspace can key off this to decide.
