Rollup merge of #101434 - JhonnyBillM:replace-session-for-handler-in-into-diagnostic, r=davidtwco
Update `SessionDiagnostic::into_diagnostic` to take `Handler` instead of `ParseSess`

Suggested by the team in [this Zulip Topic](https://rust-lang.zulipchat.com/#narrow/stream/336883-i18n/topic/.23100717.20SessionDiagnostic.20on.20Handler).

`Handler` already has almost all the capabilities of `ParseSess` when it comes to diagnostic emission, in this migration we only needed to add the ability to access `source_map` from the emitter in order to get a `Snippet` and the `start_point`. Not sure if adding these two methods [`span_to_snippet_from_emitter` and  `span_start_point_from_emitter`] is the best way to address this gap.

P.S. If this goes in the right direction, then we probably may want to move `SessionDiagnostic` to `rustc_errors` and rename it to `DiagnosticHandler` or something similar.
