Enable reloading of synonym_graph filters (#45135) 

Reloading of synonym_graph filter doesn't work currently because the search time
AnalysisMode doesn't get propagated to the TokenFilterFactory emitted by the
graph filters getChainAwareTokenFilterFactory() method. This change fixes that.

Closes #45127
