Merge of #3427 (by @mpyw) and #3614 (by @bonsairobo) (#3765)
* feat: Implement `get_transaction_depth` for drivers

* test: Verify `get_transaction_depth()` on postgres

* Refactor: `TransactionManager` delegation without BC

SQLite implementation is currently WIP

* Fix: Avoid breaking changes on `AnyConnectionBackend`

* Refactor: Remove verbose `SqliteConnection` typing

* Feat: Implementation for SQLite

I have included `AtomicUsize` in `WorkerSharedState`. Ideally, it is not desirable to execute `load` and `fetch_add` in two separate steps, but we decided to allow it here since there is only one thread writing. To prevent writing from other threads, the field itself was made private, and a getter method was provided with `pub(crate)`.

* Refactor: Same approach for `cached_statements_size`

ref: a66787d36d62876b55475ef2326d17bade817aed

* Fix: Add missing `is_in_transaction` for backend

* Doc: Remove verbose "synchronously" word

* Fix: Remove useless `mut` qualifier

* feat: add Connection::begin_with

This patch completes the plumbing of an optional statement from these methods to
`TransactionManager::begin` without any validation of the provided statement.

There is a new `Error::InvalidSavePoint` which is triggered by any attempt to
call `Connection::begin_with` when we are already inside of a transaction.

* feat: add Pool::begin_with and Pool::try_begin_with

* feat: add Error::BeginFailed and validate that custom "begin" statements are successful

* chore: add tests of Error::BeginFailed

* chore: add tests of Error::InvalidSavePointStatement

* chore: test begin_with works for all SQLite "BEGIN" statements

* chore: improve comment on Connection::begin_with

* feat: add default impl of `Connection::begin_with`

This makes the new method a non-breaking change.

* refactor: combine if statement + unwrap_or_else into one match

* feat: use in-memory SQLite DB to avoid conflicts across tests run in parallel

* feedback: remove public wrapper for sqlite3_txn_state

Move the wrapper directly into the test that uses it instead.

* fix: cache Status on MySqlConnection

* fix: compilation errors

* fix: format

* fix: postgres test

* refactor: delete `Connection::get_transaction_depth`

* fix: tests
