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.
