JIT: relax assert in fgMergeFinallyChains

In some rare and likely IL-only cases the jit may create unreachable
callfinallys. This trips up finally chain merging since it spots a
merge opportunity but no merge actually happens.

Relax the assertion checks so that `canMerge && !didMerge` is now ok.

Closes dotnet/coreclr#9651.
