Delete one or more FileChatMessageHistory message (but not all)

Checked

• I searched existing ideas and did not find a similar one
• I added a very descriptive title
• I've clearly described the feature request and motivation for it

Feature request

I need/want to delete 1 or more messages in the FileChatMessageHistory, but not all, the clear() method do that.

I understand maybe it could/should be implemented in the other BaseChatMessageHistory implementarions.

Motivation

Delete only failed ones, or just delete non relevant conversation messages, etc.

Proposal (If applicable)

I already have an implementation & tests, but could not open a PR.
