Closes #7756.
## Rationale for this change
It will be useful for the interval calculating feature to be able to
successfully determine the intervals for timestamp columns.
<!--
Why are you proposing this change? If this is already explained clearly in
the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand your
changes and offer better suggestions for fixes.
-->
## What changes are included in this PR?
Timestamp types have custom arithmetic and need special handling when
attempting to determine potential interval ranges. Change the processing of
comparison operator propagation to convert timestamp intervals into int64
intervals for processing. The results are converted back the the correct
datatype at the end of the process.
<!--
There is no need to duplicate the description in the issue here but it is

If tests are not included in your PR, please explain why (for example, are
they covered by existing tests)?

## Are there any user-facing changes?
This changes the behaviour of the interval propagation when being used with
timestamp types.
