- Memory Insights: Added analysis support for "free callstack" for an allocation (i.e. callstack when an allocation if freed). - Memory Insights: Switched CallstackId to 32 bit and moved the resolving of "id to pointer" outside of mem queries. This allows us to add the second callstack id and also ids for future metadata without increasing the size of FAllocationItem struct (from AllocationProvider). - Memory Insights: Refactored code re ThreadId and Tracker passed from AllocationAnalysis to AllocationProvider. - Memory Insights: Refactored code re CallstackProvider to map a CallstackId directly as an index into array of callstacks. #rb Johan.Berg #preflight 6201460a6773a3612898c4de [CL 18886419 by ionut matasaru in ue5-main branch]
