0.5.0 release checklist

[girlbossceo]

(maybe) Breaking stuff:

• Delete sqlite support (this has been a burden to maintain for something that we urge no one to use, isn't a default feature for a long time, and is a blocker to async database)
• Rename crate name from conduit to conduwuit

rustfmt.toml changes (huge diffs):

• Use imports_layout = "HorizontalVertical" or imports_layout = "Vertical"
• Change max_width to 100 from 120
• Revert/Delete fn_params_layout = "Compressed" to the default

Misc:

• Use clippy.toml disallowed-methods for tokio::spawn for our own runtime Handle
• Use clippy.toml disallowed-macros to disallow log::{trace,debug,info,warn,error} and tracing::{trace,debug,info,warn,error} for our own logging macro wrappers
• conduwuit-example.toml max-width to 100
