Convert attributor to IFluidDataStoreChannel (#22120)

## Description

Convert attributor to IFluidDataStoreChannel, so that it can have all
the capacity of a datastore channel like send/receive ops, summarize
etc.
This will be useful for custom attribution support where we will need
all this functionality.
Doc link for custom attribution where we will be using this to
send/receive ops:

Still working on some of the test in this PR but putting out there for
review.
