Impl InherentDataProviderExt for more tuples (#9282)

Browse Source 
* Impl InherentDataProviderExt for more tuples

Currently the inherent data provider only supports up to 4 entries due to the limit of
InherentDataProviderExt, which is not enough for a chain with more than 4 inherent data providers.
This patch simply impls InherentDataProviderExt for more tuples.

* Nit

* Apply suggestions from code review
