Fix memory leak reported in #1034

This bug was introduced when porting the original OpenCL plugin to UR. If the clCreateBufferWithProperties extension function exists, we should return even if it succeeds rather than continuing to the fallback call to clCreateBuffer.

Also add fixes from #1054:

Address coverity issue with dodgy struct-to-array casts

Also fix a similar issue coverity had with CreateProgramWithBinary which was passing array pointers straight through to the cl entry point by putting these params in local const arrays.
