Make Encode return a result (#3126)
* Make encode and encode_by_ref fallible

This only changes the trait for now and makes it compile, calling .expect() on all users. Those will be removed in a later commit.

* PgNumeric: Turn TryFrom Decimal to an infallible From

* Turn panics in Encode implementations into errors

* Add Encode error analogous to the Decode error

* Propagate decode errors through Arguments::add

This pushes the panics one level further to mostly bind calls. Those will also be removed later.

* Only check argument encoding at the end

* Use Result in Query internally

* Implement query_with functions in terms of _with_result

* Surface encode errors when executing a query.

* Remove remaining panics in AnyConnectionBackend implementations

* PostgreSQL BigDecimal: Return encode error immediately

* Arguments: Add len method to report how many arguments were added

* Query::bind: Report which argument failed to encode

* IsNull: Add is_null method

* MySqlArguments: Replace manual bitmap code with NullBitMap helper type

* Roll back buffer in MySqlArguments if encoding fails

* Roll back buffer in SqliteArguments if encoding fails

* Roll back PgArgumentBuffer if encoding fails

Generic Associated Types in Database, replacing HasValueRef, HasArguments, HasStatement (#2973)
* 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

d4329e98d4 refactor: prepare to support postgres ranges
- Remove Type bound from Encode + Decode which removes the defaults 
   for produces() and accepts(). This allows custom type implementations
   to be more flexible.

refactor(core): remove the HRTB (higher rank trait bound) on Row in the aim of improving ergonomics
* 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

6b22fb7489 Refactor HasSqlType to provide an array of compatible types.
* Intending to use in a new Row type to check types at runtime for
   dynamic queries and to guard against schema changes

 * Hoping the query! macro can utilize this to allow accepting N
   rust types for 1 sql type and returning N rust types for 1 sql
   type.
