Add params to amend-genesis command line for overriding gas limit and…

… max inflation rate in output genesis file (#11374)

This will likely be used in the forknet setup to set specific non-zero
values for max-inflation-rate and gas-limit, so adding them to the
command proactively. The mocknet/mirror toolset uses the `amend-genesis`
command to initialize the genesis for the network to start with. There
will be follow-up changes to add these extra params to the
`amend-genesis` invocation from the mocknet setup code.
