sqlx 0.9

[peterschutt]

transact-rs/sqlx#3723 introduces SqlStr as the arg type to query*() functions.

The only included implementation is SqlSafeStr for &'static str, so dynamically built queries like those found in SqlQueryFactory have to be constructed via AssertSqlSafe.

PR changes SqlQueryFactory to hold owned SqlStr and return clones of those from getters where the clones return a SqlStr that owns an Arc<&str> of the original owned String. This is the SqlStr clone impl (ref):

impl Clone for SqlStr {
    fn clone(&self) -> Self {
        Self(match &self.0 {
            Repr::Static(s) => Repr::Static(s),
            Repr::Arced(s) => Repr::Arced(s.clone()),
            // If `.clone()` gets called once, assume it might get called again.
            _ => Repr::Arced(self.as_str().into()),
        })
    }
}

SqlQueryFactory becomes:

pub(crate) struct SqlQueryFactory {
    event_table: &'static str,
    select_events: SqlStr,
    insert_event: SqlStr,
    all_events: SqlStr,
    insert_snapshot: SqlStr,
    update_snapshot: SqlStr,
    select_snapshot: SqlStr,
}

and the getters return clones of the owned SqlStrs:

impl SqlQueryFactory {
    ...
    pub fn select_events(&self) -> SqlStr {
        self.select_events.clone()
    }
    ...
}

As we are now passing event_table and snapshot_table interpolations directly into AssertSqlSafe I changed their types to impl SqlSafeStr so we are making the same safety assumption that sqlx does.

sqlx 0.9 is msrv 1.94.0 per sqlx msrv policy, so I've made the same change here.

Also, sqlx removed runtime + TLS combined features so the PR reconstructs the same combinations so that this crates features remain stable.

Thanks for this work @peterschutt , I had not followed those changes. I'll take a look this evening.
