[7.x] Attachment ingest processor: add resource_name field (#64389)

[danhermann]

In the current plugin: ingest-attachment, the text file cannot be read properly if the encode is not utf-8
and contain some non-ascii characters.

I study a little about Tika witch is used in ingest-attachment. Then I find out if we can tell Tika the file's name, it can recognize the file better. So I add an attachment options file_name, if there is a field defined as file_name, then this name will sent to Tika to improve the result.

But there is something not looks well. That's the gradle check. I wrote the unit test for reading different text using
different encoding. But seems there is a role to not commit no-utf8 things.

Backport of #64389
