* HasValueRef, HasArguments, HasStatement -> Database GATs
replace the associated types from the generic traits
`HasValueRef<'r>`, `HasArguments<'q>` and `HasStatement<'q>`
with generic associated types in `Database`
* fixup after rebase

Inlined format args make code more readable, and code more compact.
I ran this clippy command to fix most cases, and then cleaned up a few trailing commas and uncaught edge cases.
```
cargo clippy --bins --examples --benches --tests --lib --workspace --fix -- -A clippy::all -W clippy::uninlined_format_args
```
- Remove Type bound from Encode + Decode which removes the defaults
for produces() and accepts(). This allows custom type implementations
to be more flexible.
* removes the lifetime from Row
* removes MySqlQueryAs, SqliteQueryAs, etc. (no longer needed)
* introduce query_scalar
* introduce Decode::accepts to allow overriding runtime type checking
per-type (replaces TypeInfo::compatible)
* introduce Encode::produces to allow overriding the encoded type per-value
* adds a lifetime to Arguments (and introduce the HRTB HasArguments)
to support zero-copy encoding with SQLite
* renames Database::RawBuffer to HasArguments::ArgumentBuffer
* introduce Connect::connect_with to provide an ConnectOptions type
explicitly to opt-out of connection string parsing
* introduce Value and ValueRef traits to allow decoding-deferred
extraction of values from Rows
* introduce Encode::encode_by_ref and change Encode::encode to take
by-value to try and re-use memory where possible
* use thiserror to generate sqlx::Error
* [!] temporarily removes query logging
* [!] temporarily removes transactions
* tweak FromRow to accept Row by reference, should make it easier to compose FromRow impls
* rename ColumnIndex::resolve to ColumnIndex::index
* document behaviors
* implement for &serde_json::RawValue
* sqlx::types::Json<T> is a common type that all JSON-compatible databases can implement for,
postgres implements Json<T> as JSONB
* sqlx::postgres::types::PgJson<T> resolves to JSON
* sqlx::postgres::types::PgJsonB<T> resolves to JSONB
