ref-filter: add obj-type check in grab contents
Only tag and commit objects use `grab_sub_body_contents()` to grab
object contents in the current codebase. We want to teach the
function to also handle blobs and trees to get their raw data,
without parsing a blob (whose contents looks like a commit or a tag)
incorrectly as a commit or a tag. So it's needed to pass a
`struct expand_data *data` instread of only `void *buf` to both
`grab_sub_body_contents()` and `grab_values()` to be able to check
the object type.
Skip the block of code that is specific to handling commits and tags
early when the given object is of a wrong type to help later
addition to handle other types of objects in this function.
