[Sema] Fix an assert when a block captures a constexpr local

MarkVarDeclODRUsed indirectly calls captureInBlock, which creates a copy
expression. The copy expression is insulated in it's own
ExpressionEvaluationContext, so it saves, mutates, and restores MaybeODRUseExprs
as CleanupVarDeclMarking is iterating through it, leading to a crash. Fix this
by iterating through a local copy of MaybeODRUseExprs.
