ospray : add patch for upgraded dependencies

Add patch to update ospray's dependency version requirements:
- rkcommon: 1.14.0 -> 1.15.2 (remove EXACT matching)
- embree: 4.3.3 -> 4.4.0

Removing EXACT version matching for rkcommon is safe because:
1. rkcommon declares COMPATIBILITY SameMajorVersion in CMake
2. Changes from 1.14.0 to 1.15.2 are backward compatible:
   - Added shutdownTaskingSystem() function (new, non-breaking)
   - Optimized frame() math algorithm (same result, better performance)
   - Bug fixes in tasking system (improved reliability)
   - Compiler compatibility improvements (icx, ARM)
3. No API breakage: zero functions removed or signatures changed

The 1.15.2 version provides performance improvements and bug fixes
while maintaining full API compatibility with 1.14.0.
