Metal configures the query set and query index for the beginning and end of passes in pass descriptor when beginning a pass encoder, so we need to record all timestamp writes information in BeginXxxPassCmd. For the platfroms that support timestamp query, it must support timestamp write at command boundary or stage boundary, if the stage boundary is supported, use sampleBufferAttachments API for Metal implementation, otherwise simulate timestamp write using sampleCountersInBuffer API after begining a pass and before ending a pass.
