To prepare for pending ngForOf work, the dep from instructions -> query should be broken. This will enable a dep from di -> instructions while avoiding a di -> instructions -> query -> di cycle. Analyzing this cycle also uncovered another problem: the implementation of query() breaks tree-shaking through a hard dependency on DI concepts of TemplateRef, ElementRef, ViewContainerRef. This is fundamentally due to how query() can query for those values without any configuration. Instead, this fix introduces the concept by employing the strategy pattern, and redefining QueryReadType to pass a function which will return one of the above values. This strategy is then used for 'read' instead of an enum in cases where special values should be read from the DI system. PR Close #21430
