Removing another API that need not be on MultiBlock. There's generally
no need for apps to know this. If needed, we can add `...Compute`
function. This removes another API on MultiBlock that could trigger
parallel communication/synchronization.
Removing MultiBlock::GetGlobalRange API to keep things consistent with
DataSet API. Instead, one should use `FieldRangeCompute` or
`FieldRangeGlobalCompute` as appropriate.
Several MultiBlock methods take references as arguments. Generally that
is good as some of the arguments take larger data structures like
DataSet and std::vector that can be passed much faster as a reference.
However, the references were not declared const, which means that you
could not use rvalues. This is now fixed.
Updating MultiBlock to use `diy` for computing block summaries like
ranges, bounds etc. This makes it possible to MultiBlock to
work in distributed operations without explicit logic.
