When limiting blob loading, use a blob specific limit rather than a diff limit
The following discussion from !147871 (merged) should be addressed:
When we have a diff, we are also requesting the blob at the same time to do some extra identification/processing, we are just reducing the size of the blob we request, but should have no impact on the diff itself. Previously we were using a constant that was used for Diffs, but it is better to make a new constant for this.
