    User query can use global shared memory across resource group when available(Same as the PR 4843, just made the test cases stable) (#4866)
    
    1) Global shared memory will be used if the query has run out of
    	the group shared memory.
    2) The limit of memory_spill_ratio changes to [0, INT_MAX], because
    	global shared memory can be allocated, 100% limitation is not
    	make sense.
    3) Using Atomic Operation & "Compare And Save" instead of lock to
    	get high performance.
    4) Modify the test cases according to the new rules.
