chore(ffi): reduce the verbosity of the store locks and ambiguity map

[stefanceriu]

They produce hundreds of logs like

2025-02-05T12:25:02.584637Z  INFO matrix_sdk_base::store::ambiguity_map: return=false | crates/matrix-sdk-base/src/store/ambiguity_map.rs:89 | spans: live_update_handler{room_id="!XBZZPIcqcoInXjgKdL:matrix.org" focus="live"} > is_display_name_ambiguous{display_name=DisplayName { raw: "Doug", decancered: Some("doug") } users_with_display_name={"@douge:matrix.org"}}

and

2025-02-05T12:23:21.894300Z  INFO matrix_sdk_common::store_locks: aborting the previous renew task | crates/matrix-sdk-common/src/store_locks.rs:219 | spans: root > spin_lock{max_backoff=None self.lock_key="default" self.lock_holder="io.element.elementx"} > try_lock_once{self.lock_key="default" self.lock_holder="io.element.elementx"}

For the store lock renewing task, an alternative could be to lower the log level at the statement level, i.e. use trace! or debug! instead of info!. Aborting would happen often, so it's likely not desirable to put it at the info! level over all.

I think you can say the same about finding ambiguous display names. I'm thinking it's best we keep disabling them individually for a while to see where we get. At the end of it we'll have a pretty good idea on usage and we'll know better what the final fix should be 🤷

Oh damn, sorry, I'm testing something out for Ivan at the same time. Thanks for catching it!
