Add memory buffer for trap handler

[Kirpich30000]

Additional optional parameters are required for [trap-handler]:

• size (buf size in bytes) if set allocate memory buffer for trap-handler
• dump-path (file path) if set, save the contents of the trap handler buffer to a file

If size is set, the appropriate buffer info should be passed to hsaKmtSetTrapHandler():

hsaKmtSetTrapHandler(
HSAuint32 NodeId, //IN
void* TrapHandlerBaseAddress, //IN
HSAuint64 TrapHandlerSizeInBytes, //IN
void* TrapBufferBaseAddress, //IN
HSAuint64 TrapBufferSizeInBytes //IN
);

Please also fix passing of TrapHandlerSizeInBytes argument
